Kinetic mechanism of human histidine triad nucleotide binding protein 1.
Human histidine triad nucleotide binding protein 1 (hHint1) is a member of a ubiquitous and ancient branch of the histidine triad protein superfamily. hHint1 is a homodimeric protein that catalyzes the hydrolysis of model substrates, phosphoramidate and acyl adenylate, with a high efficiency. Recently, catalytically inactive hHint1 has been identified as the cause of inherited peripheral neurop...
متن کاملStructural characterization of human histidine triad nucleotide-binding protein 2, a member of the histidine triad superfamily.
The histidine triad proteins (HITs) constitute a large and ubiquitous superfamily of nucleotide hydrolases. The human histidine triad nucleotide-binding proteins (hHints) are a distinct class of HITs noted for their acyl-AMP hydrolase and phosphoramidase activity. The first high-resolution crystal structures of hHint2 with and without bound AMP are described. The differences between hHint2 and ...
متن کاملThe histidine triad superfamily of nucleotide-binding proteins.
Histidine triad (HIT) proteins were until recently a superfamily of proteins that shared only sequence motifs. Crystal structures of nucleotide-bound forms of histidine triad nucleotide-binding protein (Hint) demonstrated that the conserved residues in HIT proteins are responsible for their distinctive, dimeric, 10-stranded half-barrel structures that form two identical purine nucleotide-bindin...
متن کاملHistidine triad nucleotide-binding protein 1 (HINT1) regulates Ca(2+) signaling in mouse fibroblasts and neuronal cells via store-operated Ca(2+) entry pathway.
Recent findings indicate that histidine triad nucleotide-binding protein 1 (HINT1) is implicated in the pathophysiology of certain psychiatric disorders and also exhibits tumor suppressor properties. However, the authentic functions of HINT1 in cellular physiology and especially its role in Ca(2+) signaling remain unclear. Here, we studied Ca(2+) signaling in cultured embryonic fibroblasts deri...
متن کاملThe histidine triad protein Hint1 triggers apoptosis independent of its enzymatic activity.
Hint1 is a member of the evolutionarily conserved family of histidine triad proteins that acts as a haplo-insufficient tumor suppressor inducing spontaneous tumor formation in Hint+/- and Hint-/- mouse models. However, the molecular mechanisms for the tumor-suppressing activity are poorly defined. In this respect, we have recently shown that Hint1, by interaction with Pontin and Reptin, inhibit...
