1		6.5		GROWN FROM PEG8K PH6.5 THE PENTACOVALENT TRANSITION STATE ANALOG WAS PREPARED BY SOAKING SODIUM TUNGSTATE AND ADENOSINE INTO THE CRYSTAL. THE COMPOUNDS WERE FOUND TO BIND IN THE ACTIVE SITE OF CHAIN B. THE ACTIVE SITE OF CHAIN A IS BLOCKED BY A LATTICE CONTACT AND IS NOT AVAILABLE TO THE SUBSTRATE. THREE NEW BONDS ARE FORMED UPON SOAKING THIS MIXTURE INTO THE PKCI CRYSTALS: ONE BETWEEN THE NE OF HIS B 112 AND THE ALPHA TUNGSTATE, ONE BETWEEN THE ALPHA AND BETA TUNGSTATE IONS, AND ONE BETWEEN THE NUCLEOSIDE RIBOSE AND THE ALPHA TUNGSTATE ION.
