Overview of bacterial biotransformation of the odorless physiological malodor precursor Cys-Gly-3M3SH, which is secreted onto the surface of skin by underarm apocrine glands, subcutaneously located in the hypodermis. In Staphylococcus hominis, Cys-Gly-3M3SH is actively transported by the di-/tri-peptide transporter (DtpT) along with the movement of protons (1). Once inside the cell the terminal glycine is cleaved by a dipeptidase (PepA) to release Cys-3M3SH (2), which is metabolized by a C-S β-lyase liberating volatile 3M3SH (3), which diffuses or is exported out of the cell (4). The catabolism of Cys-Gly-3M3SH provides carbon and nitrogen as nutritional incentive in the form of glycine, ammonia and pyruvate. Image credit: Rudden et al, doi: 10.1038/s41598-020-68860-z.
