Crystallization (Commentary)

Crystallization (Comment) Organism
in complex with NADH, to 2.5 A resolution. The asymmetric unit contains a tetramer of tight dimers. Structure does not contain a cofactor-binding domain with Rossmann-fold topology. The NADH is bound in an extended conformation in each active site, in a manner that explains the pro-S specificity. Cofactor binding involves residues belonging to both subunits within the tight dimers. The results indicate the existence of a substrate discrimination mechanism, which involves electrostatic interactions Methanocaldococcus jannaschii
