bis(5'-adenosyl)-triphosphatase M-CSA #101 | The FHIT protein is a diadenosine P1, P3-triphosphate (ApppA) hydrolase that cleaves diadenosine P1, P3-triphosphate to yield AMP and ADP which is found in animals and fungi. In humans the FHIT gene is found at 3p14.2 and is thought to act as a tumour suppressor gene involved in many human cancers. It belongs to one branch of the Histidine triad (HIT) superfamily of nucleotide-binding proteins which have a conserved His-X-His-X-His-X-X (where X is a hydrophobic amino acid) motif. This was originally thought to be a zinc-ion binding site but is now believed to be the alpha-phosphate binding site [PMID:9323207]. The other branch of this superfamily consists of the HINT (histidine triad nucleotide-binding) proteins, the proposed ancestor of FHIT, galactose-1-phosphate uridylyltransferase, and other nucleotide binding proteins [PMID:9323207]. | EC: 3.6.1.29 (PDB Primary Data) EC: 3.6.2.1 (UniProt) EC: 2.7.7.51 (UniProt) EC: 3.9.1 (UniProt) |
