| Number of Residues | 1 |
| Details | ACTIVE SITE HISTIDINE RESPONSIBLE FOR FORMING THE TRANSIENT NUCLEOTIDYL PHOSPHOHISTIDYL ENZYME INTERMEDIATE DURING CATALYSIS. THE HISTIDINE IN THIS STRUCTURE IS INVOLVED IN A COVALENT ADDUCT WITH A TUNGSTATE ION WHICH IS ALSO COVALENTLY ASSOCIATED WITH A NUCLEOSIDE AND SECOND TUNGSTATE ION. THIS PHYSICALLY REPRESENTS THE PENTACOVALENT TRANSITION STATE ANALOG THOUGHT TO OCCUR IN THE REACTION OF PKCI WITH A NUCLEOTIDE DIPHOSPHATE WITH THE ALPHA TUNGSTATE ION. |
