The presence of glutamate mutase in a methanol-utilizing bacterium, Protaminobacter ruber. 1982

S Ueda, and K Sato, and S Shimizu

Cell-free extracts of a facultative methylotroph and strict aerobe, Protaminobacter ruber, could catalyze formation of beta-methylaspartate from glutamate. beta-Methylaspartate formed was further converted to mesaconate. From these results, it was found that the cells of P. ruber contained a sequential reaction system of glutamate mutase and beta-methylaspartase. The level of glutamate mutase activity was almost constant throughout the period of cultivation. When P. ruber was grown on several non-one-carbon compounds in addition to methanol as a sole carbon source, the activity of glutamate mutase was not markedly affected by the kinds of carbon sources.

UI	MeSH Term	Description	Entries
D011409	Propylene Glycols	Derivatives of propylene glycol (1,2-propanediol). They are used as humectants and solvents in pharmaceutical preparations.	Propanediols,Glycols, Propylene
D002474	Cell-Free System	A fractionated cell extract that maintains a biological function. A subcellular fraction isolated by ultracentrifugation or other separation techniques must first be isolated so that a process can be studied free from all of the complex side reactions that occur in a cell. The cell-free system is therefore widely used in cell biology.

D001419	Bacteria	One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.	Eubacteria
D014805	Vitamin B 12	A cobalt-containing coordination compound produced by intestinal micro-organisms and found also in soil and water. Higher plants do not concentrate vitamin B 12 from the soil and so are a poor source of the substance as compared with animal tissues. INTRINSIC FACTOR is important for the assimilation of vitamin B 12.	Cobalamin,Cyanocobalamin,Cobalamins,Eritron,Vitamin B12,B 12, Vitamin,B12, Vitamin
D019751	Intramolecular Transferases	Enzymes of the isomerase class that catalyze the transfer of acyl-, phospho-, amino- or other groups from one position within a molecule to another. EC 5.4.	Mutases,Transferases, Intramolecular
