'''FHIT-TRANSITION STATE ANALOG'''
===FHIT-TRANSITION STATE ANALOG===




==Overview==
<!--
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.
The line below this paragraph, {{ABSTRACT_PUBMED_9323207}}, adds the Publication Abstract to the page
(as it appears on PubMed at http://www.pubmed.gov), where 9323207 is the PubMed ID number.
