Metabolite Identification
Common NameS-Ethyl-L-cysteine
DescriptionS-Ethyl-L-cysteine belongs to the class of organic compounds known as cysteine and derivatives. Cysteine and derivatives are compounds containing cysteine or a derivative thereof resulting from reaction of cysteine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. Based on a literature review a significant number of articles have been published on S-Ethyl-L-cysteine. This compound has been identified in human blood as reported by (PMID: 31557052 ). S-ethyl-l-cysteine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically S-Ethyl-L-cysteine is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.

Enzymes

Enzyme Details
1. Cysteine-S-conjugate beta-lyase
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).
