CRYSTALLIZATION/commentary
ORGANISM
UNIPROT
LITERATURE
hanging drop vapor diffusion method, enzyme crystallized in complex with the cofactor NADP(H) and its structure is determined to 2.2 A resolution using selenomethionine single-wavelength anomalous dispersion
-
in complex with NADP(H), to 1.93 A resolution. The structure displays an empty substrate-binding, showing an open conformation of the enzyme state shortly after the release of product, presumably with bound oxidized cofactor NADP+. Amino-acid residues Lys94, His151, Trp162, Arg163, Asp176 and His180 are involved in substrate binding, catalysis or product release. The side chain of Lys94 may function as a molecular switch
