“…MSH and the MSHdependent enzymes are highly specific components as they are only found in Actinomycetes (248). The human-analog of MSH, GSH, is a protein with a similar function but which is not found in mycobacteria (249,250). Although MSH and GSH exert a similar function, they possess certain differences; while GSH is a tripeptide of gamma-glutamyl-cysteinylglycine, MSH is a cysteinyl pseudodisaccharide (101,102).…”
