FHIT-SUBSTRATE ANALOG
OverviewOverview
The histidine triad (HIT) protein family is among the most ubiquitous and, highly conserved in nature, but a biological activity has not yet been, identified for any member of the HIT family. Fragile histidine triad, protein (FHIT) and protein kinase C interacting protein (PKCI) were used, in a structure-based approach to elucidate characteristics of in vivo, ligands and reactions. Crystallographic structures of apo, substrate, analog, pentacovalent transition-state analog, and product states of both, enzymes reveal a catalytic mechanism and define substrate characteristics, required for catalysis, thus unifying the HIT family as nucleotidyl, hydrolases, transferases, or both. The approach described here may be, useful in identifying structure-function relations between protein, families identified through genomics.
