Sephchc是什么
In enzymology, SEPHCHC synthase (EC EC 2.2.1.9), encoded by menD gene in E. coli, is an enzyme that catalyzes the second step of menaquinone (vitamin K2) biosynthesis. The two substrates of this enzyme are 2-oxoglutarate and isochorismate. The products of this enzyme are 5-enolpyruvoyl-6 … See more This enzyme belongs to a family of enzymes that transfer aldehyde or ketonic groups. To be specific, this enzyme belongs to the transketolase and transaldolase families. Common names for the enzyme are: See more The structures reveal a stable dimer-of-dimers association in agreement with gel filtration and analytical studies confirm the classification of MenD in the pyruvate oxidase family.
