Description
Technical Field
The invention belongs to the technical field of microorganisms, and relates to the expression optimization of multi-subunit enzyme for synthesizing a high-added-value compound by using a lignin monomer.
Background
In view of the gradual decrease of non-renewable resources such as petroleum, natural gas, etc., the development and comprehensive utilization of renewable resources such as lignin are receiving much attention. Lignin is a natural high molecular compound, widely present in higher plant cells, and is a second-order biomass in nature. The lignin is a natural aromatic polymer formed by connecting phenylpropane units through C-O-C and C-C bonds and carrying out catalytic dehydrogenation polymerization and free radical polymerization of enzyme. It is believed from a prior view that lignin building blocks mainly comprise: p-Hydroxyphenyl propane (p-Hydroxyphenyl propane/H), Guaiacyl propane (Guaiacryl/G) and Syringyl propane (Syringyl/S). Lignin forms various aromatic compounds after thermochemical conversion and biological conversion, most compounds also contain methyl, after microbial demethylation, intermediate metabolites such as catechol, protocatechuic acid, 3,4, 5-trihydroxybenzoic acid and the like are formed, and then the intermediate metabolites can further enter central carbon metabolism and downstream high-added-value product generation, so that demethylation of a monomer compound from lignin is an important link for lignin utilization.
Many studies have been made to establish cell factories for efficient utilization of lignin and biorefinery of high value-added compounds, such as in the fields of medicine, biofuel, food and chemical industry, by modifying microorganisms. Genetic modification of microorganisms is common, but in the process of genetic modification, due to modification of endogenous genes and insertion of exogenous genes, metabolic flow imbalance is caused, growth is delayed, and yield of target compounds is low. In order to solve the imbalance of metabolic flux, accelerate strain optimization and improve the production of various high-value bio-based chemicals, technologies such as multivariate modular metabolic engineering (multivariate metabolic engineering), modular co-culture engineering (modular co-culture engineering) and spatio-temporal and genome integration have been widely used. The above techniques, focusing on one or more metabolic pathways, focus on the regulation of expression of multiple enzymes, while there is little interest in single-function multi-subunit enzymes.
The P450 protein is a multifunctional enzyme and can catalyze monomer compounds from various lignin sources. O-demethylation, consisting of the cytochrome P450 protein (GcoA) of the CYP255A family and a three-domain constitutive reductase (GcoB). By optimizing the multicomponent O-demethylase double subunits GcoA and GcoB, the expression ratio and enzyme activity, growth rate and the like of the enzymes in cells are researched, and a foundation is provided for the utilization of aromatic compounds.
Catechol (hereinafter referred to as CAT) is a white crystalline compound which is soluble in water, ethanol, diethyl ether, benzene, toluene, and chloroform, and is easily soluble in pyridine and an alkaline aqueous solution. Is an important chemical intermediate, and is mainly used for producing antioxidants, tanning agents, spices and the like. For example, in the aspect of pesticide production, the compound is used for synthesizing diethofencarb, propoxur, carbofuran and the like; in the aspect of medical synthesis, the medicine is used for preparing the cumin epinephrine, the berberine and the like. At present, the industrial production of catechol is mainly a chemical synthesis method, phenol is taken as a raw material, strong acid or hydrogen peroxide is taken as a catalyst, but the method has the factors of harsh reaction conditions, low conversion rate, more byproducts, complex components, complex product separation process, serious environmental pollution and the like.
It has been reported in the literature (Production of carbonate from Benzoate by the Wild Strain metabolites Ba-0323and charaterization of Its salts 1,2-Dioxygenase, Bioscience, Biotechnology, and Biochemistry,2014, 65:9,1957 and 1964) that Ralstonia sp.Ba-0323 can convert sodium Benzoate to form 1.9mg/ml Catechol.
catechol-O-sulfate is an aryl sulfate, which is catechol having one of the two hydroxyl groups substituted with a sulfo group. It is a member of the aryl sulfates and phenols. The catechol-O-sulfate salt may improve cardiac muscle cell beating and Ca2+ signaling in response to sustained stimulation of β -adrenergic receptors by promoting cardioprotection in the following manner.
Little has been reported about the biosynthesis of catechol-O-sulfate, and only ASTB-OM2 (aryl sulfotransferase B) catalyzes catechol to produce catechol-O-sulfate (Loop engineering of aryl sulfotransferase B for improving catalytic performance in a metabolic substrate, Catal. Sci. technol.,2020,10, 2369).
Hongbaolin (Purpurogenin) is a natural phenol extracted from nuts and oak bark, and has strong Xanthine Oxidase (XO) inhibitory activity, and IC of 0.2 μ M. The rhodophenol has antioxidant, anticancer and anti-inflammatory properties. Xanthine oxidase is the terminal enzyme of human purine catabolism, catalyzing the oxidation of hypoxanthine and xanthine. These reactions produce uric acid and active oxygen such as superoxide anion and hydrogen peroxide. It is well known that the onset of gout is due to an excessive accumulation of blood uric acid: this excessive accumulation is considered to be associated with eating habits, and therefore, although gout is a classic disease, it is now recognized as a lifestyle-related disease, and more patients are recently suffering from the disease. Cardiovascular disease is another lifestyle-related disease that is well known to be associated with oxidative stress caused by superoxide anions, hydrogen peroxide, nitric oxide and its metabolites (hydroxyl radicals, peroxynitrite, etc.). Therefore, inhibition of xanthine oxidase overworking is important for prevention of such lifestyle-related diseases. Repazol inhibits the production of proinflammatory cytokines by inhibiting the mRNA and protein expression of IL-1 β and TNF- α in LPS stimulated BV2 microglia. Erythrophenol exerts an anti-inflammatory effect by inhibiting LPS stimulated BV2 microglia phosphatidylinositol 3-kinase/Akt and mitogen-activated protein kinase signaling pathways. Honegyphenol inhibits esophageal squamous cell carcinoma by directly targeting the mitogen-activated protein kinase 1/2(MEK1/2) signaling pathway. Therefore, the synthesis of the rhodophenol is of great significance. The reported synthesis of rhodophenol has focused on chemical methods.
