Effects of nucleotides on the interaction of renin with GlcNAc 2-epimerase (renin binding protein, RnBP).


Renin binding protein (RnBP), a cellular renin inhibitor, was identified as an enzyme, GlcNAc 2-epimerase. Recombinant RnBP inhibited porcine renin activity in a dose dependent manner. However, the inhibition was neutralized by nucleotides, such as ATP, dATP, dGTP, dCTP or dTTP. Moreover, ATP inhibited the formation of hetero-complex of renin with RnBP… (More)
