WebFig. 3 Organization of catalytic and regulatory domains of PLP enzymes in the β family. Protein chains are aligned at the lysine residue that binds PLP in O-acetylserine sulfhydrylase from Salmonella typhimurium, the tryptophan synthase β subunit from S. typhimurium, and biosynthetic threonine deaminase from E. coli and CBS from T. cruzi, … Cystathionine-β-synthase, also known as CBS, is an enzyme (EC 4.2.1.22) that in humans is encoded by the CBS gene. It catalyzes the first step of the transsulfuration pathway, from homocysteine to cystathionine: L-serine + L-homocysteine $${\displaystyle \rightleftharpoons }$$ L … See more The systematic name of this enzyme class is L-serine hydro-lyase (adding homocysteine; L-cystathionine-forming). Other names in common use include: • β-thionase, • cysteine synthase, See more The human enzyme cystathionine β-synthase is a tetramer and comprises 551 amino acids with a subunit molecular weight of 61 kDa. It displays a modular organization of … See more Down syndrome is a medical condition characterized by an overexpression of cystathionine beta synthase (CBS) and a low level of homocysteine in the blood. It has been … See more Cystathionine beta synthase (CBS) is involved in oocyte development. However, little is known about the regional and cellular expression patterns of CBS in the ovary and research … See more Transsulfuration, catalyzed by CBS, converts homocysteine to cystathionine, which cystathione gamma lyase converts to See more Allosteric activation of CBS by adoMet determines the metabolic fate of homocysteine. Mammalian CBS is activated 2.5-5-fold by AdoMet with a dissociation constant of … See more The genes that control CBS enzyme expression may not operate at 100% efficiency in individuals who have one of the SNPs ( See more WebJun 24, 2024 · Using a combination of biochemistry and cryo-electron microscopy, we characterized the first enzyme of the transsulfuration pathway, cystathionine β-synthase (MtbCbs) in Mtb. We demonstrated that Mtb Cbs is a heme-less, pyridoxal-5'-phosphate-containing enzyme, allosterically activated by S -adenosylmethionine (SAM). song shallow
