the allosteric site for binding of glc-6-p has previously been shown to reside in the n-terminal half of the molecule , and it is suggested that the antagonism of inhibition by glc-6-p ( or its analog ) by these anionic ligands results from interaction with an anion binding site for which the 6-phosphate group of inhibitory hexose 6-phosphates must compete .
