Description

Apparatus and method for performing genome sequence analysis and data management

The present invention relates to a genome analysis system, and more particularly, to a system and method for automatically executing a series of processes for analyzing microbial genome sequences and constructing analysis results into a database.

The genome is a compound word of gene and om, which refers to the sum of all genes in an organism. In general, prokaryotic cells have complex structures of genes, whereas eukaryotes have relatively simpler genes than multicellular organisms. Thus, many studies have been conducted on eukaryotic organisms, and it is relatively easy to predict its function or confirm its function.

Functional genomics (or functional genomics) refers to identifying the location and function of genes in a genome and identifying pathways. Currently, functional genomics research can be divided into two technologies. The first technique is to identify the position of a gene in the genome. As described above, in the case of prokaryotes, the structure of genes is relatively simple, and since the research has been conducted for a long time, many programs for predicting prokaryotic genes have been developed. Among them, Glimmer (Gene Locator and Interpolated Markov Modeler) 2.02 is known to predict the prokaryotic gene most accurately by using the Hidden Markov model. The second technique is to analyze the function and pathway of the identified gene. Currently, a method of similarity search is used as a method for confirming the function of a gene, and a method through BLAST search is most widely used. This method finds the similarity between the previously studied sequence and the target sequence by searching for similarity between the sequence to be compared and the reference database. You can perform comparisons in bulk by changing the target database.

However, since the gene prediction and sequence similarity search programs and the databases used for data analysis are provided separately from each other, gene prediction, function analysis, path identification, and data storage and retrieval functions must be performed separately. There is no limit. Therefore, there is a difficulty in automating microbial sequencing and using a user.

The technical problem to be achieved by the present invention is to integrate the existing microbial gene prediction and sequence similarity search program and the existing database, the time required for gene prediction, and the function and path analysis through sequence similarity search The present invention provides a genome sequencing and database management system and a method for efficiently reducing the time required.

Another object of the present invention is to provide a computer-readable recording medium having recorded thereon a program for executing the method on a computer.

How to analyze and manage your data. The method of claim 11, Wherein said user information, said genomic sequence information, and said search clue are input from at least one or more clients connected via a network. The method of claim 11, The method of genome sequencing and data management further comprises (e) providing the sequencing results and the search results to the client via the network. The method of claim 11, wherein the second database, A Cluster of Orthologous Groups (COG) function information table for storing function information for each gene; A COG path information table in which path information for each gene is stored; And Genome sequence analysis and data management method comprising a domain information table for storing domain information for each gene. The method of claim 14, wherein the first database, A similarity search result table connected to the COG function information table and the COG path information table and receiving the function information and the path information for each gene; And And a domain search result table connected to the domain information table and receiving the domain information for each gene. The method of claim 11, wherein step (b) comprises: (b-1) predicting a gene portion from the genomic sequence information; (b-2) searching for a gene similar in sequence to the part predicted by the gene from the second database; And (b-3) performing a domain search for the gene from the second database. The method of claim 11, In step (d), a function-specific search for searching genes classified into a predetermined group by function, a path-specific search for searching genes classified into a predetermined group by path, and a gene corresponding to a keyword input from a user Genome sequence analysis and data management method characterized in that to perform any one of the keyword search. The method of claim 11, The first database stores the entry information of the second database in which the corresponding data is stored, instead of storing the detailed information of the gene searched in the step (d) itself. . (a) accepting genomic sequence information from a user; (b) predicting a gene portion from the genomic sequence information; (c) searching for genes that are similar in sequence to the predicted portion of the gene portion from a first database in which verified large amounts of gene sequence related data are stored; (d) performing a domain search for the gene from the first database; (e) extracting detailed information about the gene from the first database when the search results performed in the steps (c) and (d) show that the gene has a predetermined level or more similarity; And (f) storing the result extracted in step (e) as a genome analysis result in a second database. The method of claim 19, Wherein the genomic sequence information is input from at least one or more clients connected through a network. The method of claim 19, The genomic sequencing method may further include (g) providing the analysis result of the genomic sequence information to the client through the network. The method of claim 19, The genome sequencing method may further manage user information accessible to the second database to maintain security between users. (a) selecting one of a function, path, or keyword search by a user; (b) if a function-specific search is selected in step (a), performing a gene search for any function category among a plurality of function categories from a first database in which the genomic sequencing results obtained by the experiment are stored; (c) if a search for each path is selected in step (a), performing a gene search for any path category among a plurality of path categories from the first database; (d) if a keyword search is selected in step (a), performing a gene search for the keyword input from the user from the first database; (e) displaying the search results performed in steps (b), (c) and (d); And (f) if any gene is selected from the search results displayed in step (e), the detailed information about the gene is searched and displayed from a second database in which a large amount of verified gene sequence related data is stored. Gene search method characterized in that. The method of claim 23, The search clue for performing the function, path, and keyword search is input from at least one or more clients connected through a network. The method of claim 23, The search results performed in the steps (e) and (f) are displayed on the client side via the network. A computer-readable recording medium having recorded thereon a program for executing the method of any one of claims 11 to 25 on a computer.
