Publication Abstract from PubMed Histidine triad nucleotide-binding protein (HINT), a dimeric purine nucleotide-binding protein from rabbit heart, is a member of the HIT (histidine triad) superfamily which includes HINT homologues and FHIT (HIT protein encoded at the chromosome 3 fragile site) homologues. Crystal structures of HINT-nucleotide complexes demonstrate that the most conserved residues in the superfamily mediate nucleotide binding and that the HIT motif forms part of the phosphate binding loop. Galactose-1-phosphate uridylyltransferase, whose deficiency causes galactosemia, contains tandem HINT domains with the same fold and mode of nucleotide binding as HINT despite having no overall sequence similarity. Features of FHIT, a diadenosine polyphosphate hydrolase and candidate tumour suppressor, are predicted from HINT-nucleotide structures. Crystal structures of HINT demonstrate that histidine triad proteins are GalT-related nucleotide-binding proteins.,Brenner C, Garrison P, Gilmour J, Peisach D, Ringe D, Petsko GA, Lowenstein JM Nat Struct Biol. 1997 Mar;4(3):231-8.
