Structure-based analysis of catalysis and substrate definition in the HIT protein family.
C.D.Lima, M.G.Klein, W.A.Hendrickson.
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.

Figure 2.
Fig. 2. Stereo views of PKCI in (A) apo, (B) AMP-CP substrate analog, (C) adenosine-tungstate transition-state^ analog, and (D) AMP product-bound forms. The region shown was selected to highlight interactions between the ligand and^ protein residues surrounding one of the two equivalent ligand-binding sites in the HIT homodimer. A subset of residues is shown superimposed^ on the C backbone cardinal spline of each respective structure. Hydrogen bonds are denoted by dotted lines. The tryptophan shown is in the COOH-terminal tail of the other protomer. Figure generated^ with Setor (15).

Fig. 3. Schematic diagram of FHIT in (A) apo, (B) AMP-CP substrate analog, (C) adenosine-tungstate transition-state^ analog, and (D) adenosine-sulfate product complexed forms. As in Fig. 2, hydrogen-bonding interactions are depicted by dotted^ lines. A subset of residues is shown superimposed on the C backbone^ cardinal spline of each respective structure.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
