>gnl|CDD|130817 TIGR01756, LDH_protist, lactate dehydrogenase.  This model
           represents a family of protist lactate dehydrogenases
           which have aparrently evolved from a recent protist
           malate dehydrogenase ancestor. Lactate dehydrogenase
           converts the hydroxyl at C-2 of lactate to a carbonyl in
           the product, pyruvate. The preference of this enzyme for
           NAD or NADP has not been determined. A critical residue
           in malate dehydrogenase, arginine-91 (T. vaginalis
           numbering) has been mutated to a leucine, eliminating
           the positive charge which complemeted the carboxylate in
           malate which is absent in lactate. Several other more
           subtle changes are proposed to make the active site
           smaller to accomadate the less bulky lactate molecule.
