Amino acid residues that determine functional specificity of NADP
... which are known specificity determinants (115Asn, 232Asn, 233Ile) and some are new ones (103Leu). Analysis of the intersubunit contacts leads to identification of two spatial clusters of contacting SDPs, one formed by 305Asn and 308Tyr from both subunits (305Asn and 308Tyr from different subunits may ...
