| Description | The Histidine Triad (HIT) motif, His-x-His-x-His-x-x (x, a hydrophobic amino acid) was identified as being highly conserved in a variety of organisms [, ]. On the basis of sequence, substrate specificity, structure, evolution and mechanism, HIT proteins are classified into three branches: the Hint branch, which consists of adenosine 5' -monophosphoramide hydrolases, the FHIT branch, that consists of diadenosine polyphosphate hydrolases, and the GalT branch consisting of specific nucloside monophosphate transferases [, ]. In budding yeast Hnt1 has been shown to have adenosine monophosphoramidase activity and function as positive regulators of Cdk7/Kin28 in vivo [ , ]. FHIT plays a very important role in the development of tumours. In fact, FHIT deletions are among the earliest and most frequent genetic alterations in the development of tumours [, ]. The third branch of the HIT superfamily, which includes GalT homologues, contains a related His-X-His-X-Gln motif and transfers nucleoside monophosphate moieties to phosphorylated second substrates ratherthan hydrolysing them [ ]. |
