Cystathionine gamma-synthase (CGS) catalyses the first step of the transsulfuration pathway that converts l-cysteine to l-homocysteine in bacteria, whereas this pathway is absent in human. In this report, we identified a new metB gene from Helicobacter pylori strain SS1, and

Mutations were found which enable Escherichia coli K-12 to form homocysteine in the absence of cystathionase. The formation of homocysteine in the mutant strains required cystathionine gamma-synthetase, the metB gene product, but bypassed the normal intermediate cystathionine. It is concluded

Volatile sulfur compounds are key flavor compounds in several cheese types. To better understand the metabolism of sulfur-containing amino acids, which certainly plays a key role in the release of volatile sulfur compounds, we searched the genome database of Lactobacillus

O-Succinyl-l-homoserine (OSH) is an important platform chemical in production of C4 chemicals such as succinic acid, homoserine lactone, γ‑butyrolactone, and 1,4‑butanediol. The production of OSH through chemical method or the current engineering strain is difficult and not optimal, and thereby

Cysteine and methionine biosynthesis was studied in Pseudomonas putida S-313 and Pseudomonas aeruginosa PAO1. Both these organisms used direct sulfhydrylation of O-succinylhomoserine for the synthesis of methionine but also contained substantial levels of O-acetylserine sulfhydrylase (cysteine synthase) activity. The enzymes
