Protein Family Models

This domain is found in the C-terminal region of Shikimate 5'-dehydrogenase (SDH) present in Methanocaldococcus jannaschii. SDH catalyses the NADPH-dependent reduction of 3-dehydroshikimate to shikimate in the shikimate pathway. The domain is found just after the C-terminal domain (Pfam:PF01488) which is responsible for NADP binding [1]. [1]. 19215302.

shikimate dehydrogenase family protein similar to (NADP(+)) dependent shikimate dehydrogenase that catalyzes the reversible reduction of 3-dehydroshikimate (DHSA) to yield shikimate (SA), part of the chorismate biosynthesis pathway and NAD(+) dependent quinate dehydrogenase that catalyzes the conversion of L-quinate into 3-dehydroquinate, as part of the aromatic compound metabolism

This HMM finds proteins from prokaryotes and functionally equivalent domains from larger, multifunctional proteins of fungi and plants. Below the trusted cutoff of 180, but above the noise cutoff of 20, are the putative shikimate dehydrogenases of Thermotoga maritima and Mycobacterium tuberculosis, and uncharacterized paralogs of shikimate dehydrogenase from E. coli and H. influenzae. The related enzyme quinate 5-dehydrogenase scores below the noise cutoff. A neighbor-joining tree, constructed with quinate 5-dehydrogenases as the outgroup, shows the Clamydial homolog as clustering among the shikimate dehydrogenases, although the sequence is unusual in the degree of sequence divergence and the presence of an additional N-terminal domain.
