Shikimate 5-dehydrogenase; This model 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 Clamydi [...]

3-deoxy-7-phosphoheptulonate synthase; This model describes one of at least three types of phospho-2-dehydro-3-deoxyheptonate aldolase (DAHP synthase). This enzyme catalyzes the first of 7 steps in the biosynthesis of chorismate, that last common precursor of all three aromatic amino acids and of PABA, ubiquinone and menaquinone. Some members of this family, including an experimentally characterized member from Bacillus subtilis, are bifunctional, with a chorismate mutase domain N-terminal to this region. The member of this family from Synechocystis PCC 6803, CcmA, was shown to be esse [...]

Trigger factor is a ribosome-associated molecular chaperone and is the first chaperone to interact with nascent polypeptide. Trigger factor can bind at the same time as the signal recognition particle (SRP), but is excluded by the SRP receptor (FtsY). The central domain of trigger factor has peptidyl-prolyl cis/trans isomerase activity. This protein is found in a single copy in virtually every bacterial genome. [Protein fate, Protein folding and stabilization]; High confidence in function and specificity.

ATP + pyruvate = ADP + phosphoenolpyruvate; High confidence in function and specificity; Belongs to the pyruvate kinase family.

Pyruvate dehydrogenase (NADP(+)); Pyruvate + CoA + NADP(+) <=> acetyl-CoA + CO(2) + NADPH; High confidence in function and specificity.

Putative membrane protein; Involved in protein export. Participates in an early event of protein translocation; Belongs to the SecG family.

Shikimate kinase; Catalyzes the specific phosphorylation of the 3-hydroxyl group of shikimic acid using ATP as a cosubstrate; Belongs to the shikimate kinase family.

Chorismate synthase; Catalyzes the anti-1,4-elimination of the C-3 phosphate and the C-6 proR hydrogen from 5-enolpyruvylshikimate-3-phosphate (EPSP) to yield chorismate, which is the branch point compound that serves as the starting substrate for the three terminal pathways of aromatic amino acid biosynthesis. This reaction introduces a second double bond into the aromatic ring system.

50S ribosomal protein L13; This protein is one of the early assembly proteins of the 50S ribosomal subunit, although it is not seen to bind rRNA by itself. It is important during the early stages of 50S assembly.
