'''CIRCULARLY PERMUTED PHOSPHOGLYCERATE KINASE FROM YEAST: PGK P72'''<br />


==Overview==
==CIRCULARLY PERMUTED PHOSPHOGLYCERATE KINASE FROM YEAST: PGK P72==
The crystallographic structure of a circularly permuted form of yeast PGK, 72p yPGK, has been determined to a resolution of 2.3 A by molecular, replacement. In this engineered protein, the C- and N-terminal residues of, the wild-type protein are directly connected by a peptide bond and new N-, and C-terminal residues are located within the N-terminal domain. The, overall fold of the protein is very similar to that of the wild-type, protein, directly demonstrating that the continuity of a folding unit is, not relevant to the folding process of the whole protein. Only limited, structural changes were observed: these were in the regions associated, with the new connection, in a long flexible loop in the permuted domain, and in the vicinity of Arg38, a functionally important residue. The, relative positions of the two domains suggested that this permuted protein, adopts one of the most open/twisted conformations seen amongst PGKs of, known structure. The effect of the mutation on the functional properties, is more easily accounted for by a restriction of hinge-bending motion than, by structural changes in the protein.
