Common NameMycothiol
DescriptionMycothiol is a low-molecular-weight thiol compound belonging to the chemical class of thiol antioxidants. It plays a crucial role in the redox biology of mycobacteria, particularly in Mycobacterium tuberculosis, where mycothiol cysteine ligase (MshC) is essential for its biosynthesis and represents a potential target for novel anti-mycobacterial drug development (PMID:40913853 ). Additionally, mycothiol disulfide reductase has been identified as a target for anti-nontuberculous mycobacterial drug candidates, with its crystal structure determined from Mycobacterium abscessus (PMID:40972502 ). The expression of mycothiol oxidoreductase MscR is linked to resistance mechanisms against electrophilic stressors, indicating its significance in cellular defense (PMID:40799345 ). Furthermore, treatment of Mtb cells with electrophiles reveals profound thiol stress and rapid depletion of mycothiol (PMID:39625876 ; PMID:39372785 ). Mycothiol's involvement in various metabolic pathways, including enhanced H2O2 scavenging and iron chelation, highlights its biological relevance (PMID:40538044 ). Despite its importance, literature on mycothiol remains limited, indicating a need for further exploration of its functions and applications in mycobacterial research.
