| Type: | Family | Name: | Cysteine synthase |
| Description: | Cysteine synthase (also known as O-acetylserine (thiol)-lyase or O-acetyl-L-serine sulfhydrylase) is the enzyme responsible for the formation of cysteine from O-acetyl-serine and hydrogen sulphide with the concomitant release of acetic acid. In bacteria such two forms of the enzyme are known (genes cysK and cysM) [, ]. CysM differs from CysK in that it can also use thiosulphate instead of sulphide, to produce cysteine. Beta-cyanoalanine synthase is a mitochondrial cysteine synthase-like protein from plants []. It has cysteine synthase activity, but the cyanoalanine synthesis reaction is more efficient than the cysteine synthase activity. | Short Name: | Cys_synth |
