Synonyms
  1. C-S lyase
  2. Cystathionine beta-lyase
  3. CBL
Gene Name METC
Protein Type Unknown
Biological Properties
General Function Not Available
Specific Function Catalyzes the cleavage of the cysteine-S bond in various cysteine-S-conjugates (PubMed:17191898, PubMed:18515361). Cleaves L-cystathionine, as well as S-substituted cysteine conjugates S-benzyl-L-cysteine and S-ethyl-L-cysteine (PubMed:17191898). Releases four human body odoriferous sulfanylalkanols: 3-methyl-3-sulfanylhexan-1-ol (3M3SH), 3-sulfanylhexan-1-ol, 2-methyl-3-sulfanylbutan-1-ol and 3-sulfanylpentan-1-ol; the release is obtained after the sequential hydrolysis of the Cys-Gly bond of the odorless Cys-Gly-S-conjugate precursors by the dipeptidase TpdA, then the cleavage of the resulting Cys-S-conjugates by MetC (PubMed:17191898, PubMed:18515361).
