Crystal structure of YFH7 from Saccharomyces cerevisiae: a putative P-loop containing kinase with a circular permutation.
Overview
Genome sequencing projects have revealed that P-loop proteins are highly, represented in all organisms and that many of them have no attributed, function. They are characterized by a conserved nucleotide-binding domain, and carry different activities implicated in many cellular processes., Saccharomyces cerevisiae YFH7 is one of these P-loop proteins of unknown, function. In this work we tried to integrate bioinformatics, structure, and enzymology to discover the function of YFH7. Sequence analysis, revealed that yeast YFH7 is a yeast-specific protein showing weak, similarity with the phosphoribulokinase/uridine kinase/bacterial, pantothenate kinase (PRK/URK/PANK) subfamily of P-loop containing kinases., A large insertion of about 100 residues distinguishes YFH7 from other, members of the family. The 1.95 A resolution crystal structure of YFH7, solved using the SAD method confirmed that YFH7 has a fold similar to the, PRK/URK/PANK family, with the characteristic core, lid, and NMP(bind), domains. An additional alpha/beta domain of novel topology corresponds to, the large sequence insertion. Structural and ligand binding analysis, combined with enzymatic assays suggest that YFH7 is an ATP-dependent small, molecule kinase with new substrate specificity. Proteins 2007.
