cysteine synthase A

This model distinguishes cysteine synthase A (CysK) from cysteine synthase B (CysM). CysM differs in having a broader specificity that also allows the use of thiosulfate to produce cysteine thiosulfonate.

Gene:: cysK

GO Terms:

Molecular Function:: cysteine synthase activity (GO:0004124)

Biological Process:: cysteine biosynthetic process from serine (GO:0006535)

cysteine synthase

This model discriminates cysteine synthases (EC 2.5.1.47) (both CysK and CysM) from cystathionine beta-synthase, a protein found primarily in eukaryotes and carrying a C-terminal CBS domain lacking from this protein. Bacterial proteins lacking the CBS domain but otherwise showing resemblamnce to cystathionine beta-synthases and considerable phylogenetic distance from known cysteine synthases were excluded from the seed and score below the trusted cutoff.
