This family contains both shikimate and quinate dehydrogenases. Shikimate 5-dehydrogenase catalyses the conversion of shikimate to 5-dehydroshikimate. This reaction is part of the shikimate pathway which is involved in the biosynthesis of aromatic amino acids. Quinate 5-dehydrogenase catalyses the conversion of quinate to 5-dehydroquinate. This reaction is part of the quinate pathway where quinic acid is exploited as a source of carbon in prokaryotes and microbial eukaryotes. Both the shikimate and quinate pathways share two common pathway metabolites 3-dehydroquinate and dehydroshikimate. Discusses the pentafunctional AROM multi-domain protein, which possesses a shikimate 5-dehydrogenase enzyme. The AROM protein catalyses steps two to six in the shikimate pathway in many microbial eukaryotes. [1]. 7556173. The molecular biology of multidomain proteins. Selected examples.

alanine dehydrogenase catalyzes the NAD(+)-dependent oxidative deamination of L-alanine to pyruvate, and the reverse reaction, the reductive amination of pyruvate; alanine dehydrogenase catalyzes the reversible oxidative deamination of L-alanine to pyruvate

The family of known L-alanine dehydrogenases (EC 1.4.1.1) includes representatives from the Proteobacteria, Firmicutes, Cyanobacteria, and Actinobacteria, all with about 50 % identity or better. An outlier to this group in both sequence and gap pattern is the homolog from Helicobacter pylori, an epsilon division Proteobacteria, which must be considered a putative alanine dehydrogenase. In Mycobacterium smegmatis and M. tuberculosis, the enzyme doubles as a glycine dehydrogenase (1.4.1.10), running in the reverse direction (glyoxylate amination to glycine, with conversion of NADH to NAD+). Related proteins include saccharopine dehydrogenase and the N-terminal half of the NAD(P) transhydrogenase alpha subunit. All of these related proteins bind NAD and/or NADP.
