LGUL_HUMAN Catalyzes the conversion of hemimercaptal, formed from methylglyoxal and glutathione, to S-lactoylglutathione. Involved in the regulation of TNF-induced transcriptional activity of NF-kappa-B.[1]

Publication Abstract from PubMed

Human glyoxalase I (hGLO I) is an enzyme for detoxification of methylglyoxal (MG) and has been considered an attractive target for the development of new anticancer drugs. In our previous report, the GLO I inhibitor TLSC702 induced apoptosis in tumor cells. Here, we determined the crystal structures of hGLO I and its complex with TLSC702. In the complex, the carboxyl O atom of TLSC702 is coordinated to Zn(2+) , and TLSC702 mainly shows van der Waals interaction with hydrophobic residues. In the inhibitor-unbound structure, glycerol, which has similar functional groups to MG, was bound to Zn(2+) , indicating that GLO I can easily bind to MG. This study provides a structural basis to develop better anticancer drugs.

Crystal structures of human glyoxalase I and its complex with TLSC702 reveal inhibitor binding mode and substrate preference.,Usami M, Ando K, Shibuya A, Takasawa R, Yokoyama H FEBS Lett. 2022 Apr 1. doi: 10.1002/1873-3468.14344. PMID:35363883[2]
