Abstract
The present invention relates to produce R- (+) -3- (3,4- dihydroxy phenyl) -2 hydroxy propanoic acid using Proteus microorganism conversion levodopa.This method process is simple, has important industrial application value.
Description
Technical field
The present invention produces danshensu using proteus conversion levodopa, belongs to industrial microorganism field.
Background technique
Danshensu, scientific name R- (+) -3- (3,4- dihydroxy phenyl) -2 hydroxy propanoic acid, D- (+)-β-(3,4- dihydroxy benzenes
Base) lactic acid, English name are as follows: Danshensu, (R)-(+) -3- (3,4-Dihydroxyphenyl)-lactic acid, (R) -
(+) -3- (3,4-Dihydroxyphenyl) -2-hydroxypropanoic acid is a kind of dextrorotation phenolic acid compound.
Danshensu is that important in Salvia miltiorrhiza Bge water extract wants effective ingredient, and the country obtained simultaneously from Salvia miltiorrhiza Bge water extract in 1980
Identify structure (research of Determination of water-soluble active constituents of radix, the structure of II .D (+) β (3,4- dihydroxy phenyl) lactic acid, Shanghai
One medical college's journal, 1980,05 (7), 384-385), it is various research shows that danshensu have important pharmacological effect effect,
Treatment of cardiovascular and cerebrovascular disease etc. has unique treatment effect.
Current danshensu, which is mainly extracted from Radix Salviae Miltiorrhizae, obtains (patent CN200810038853.9).Danshensu is in Radix Salviae Miltiorrhizae
Content is lower, and danshensu planting cost height and limits throughput, therefore not only price is high but also much can not for current danshensu
Meets the needs of market.Patent CN201310559498.0 proposes a kind of building bacillus coli gene engineering drawing and utilizes glucose
The method that fermentation produces danshensu, since metabolic pathway of synthesizing relates to the use of hydroxylase, which is easy to make metabolic process product
The yield of danshensu is aoxidized and influenced, simultaneously because Escherichia coli fermentation is high oxygen process, can also aoxidize danshensu, therefore work as
Preceding this method yield is lower, and cost will be higher than plant extract process.Patent CN201210190171.6 proposes the red phenol of hydrolysis
The method of sour B production danshensu, tanshin polyphenolic acid B need to be extracted from Radix Salviae Miltiorrhizae, and chemical hydrolysis process has a large amount of side reactions, same uncomfortable
For large-scale production.The catalyst of chirality synthesis danshensu (patent CN201210420488.4) is prohibitively expensive, currently also only
Rest on laboratory level.
Significant application value based on danshensu, this patent are proposed using Proteus microorganism conversion levodopa
Produce the scheme of danshensu.Levodopa is also named: L-3- (3,4- dihydroxy phenyl) alanine (L-DOPA, L-3,4-
dihydroxyphenylalanine).Current levodopa can produce (Overview from plant extract also microbial fermentation
On the biotechnological production of L-DOPA, 2015, ApplMicrobiol Biotechnol,
99:575-584), abundant raw material is easy to get.
Proteus (Proteus) be it is widely distributed in nature, such as soil, water, rubbish, spoilage organism and people or
Microorganism in the enteron aisle of animal.Existing 5 kinds: proteus vulgaris (Proteus vulgaris), proteus mirabilis
(Proteus mirabilis), glutinous proteus (Proteus myxofaciens), Pan Shi proteus (Proteus are produced
) and Hao Shi proteus (Proteus hauseri) penneri.Proteus has powerful oxidative deamination ability
(Sherris Medical Microbiology, 2004,4th ed.), levodopa can by proteus oxidative deamination at
3,4- dihydroxyphenyl pyruvic acids (3- (3,4-dihydroxyphenyl) -2-oxopropanoic acid), are then then reduced into
Danshensu.Although 3,4- dihydroxyphenyl pyruvic acids are more direct substrates, but expensive and unstable, therefore levodopa
It is optimal substrate.Proteus is a kind of facultative anaerobic bacteria, and production Radix Salviae Miltiorrhizae can be converted under anaerobic condition or aerobic condition
Element has the characteristics that high conversion and high-purity.
Summary of the invention
The present invention produces danshensu by culture Proteus microbial cells, conversion levodopa, and technical solution is such as
