Glutamate-1-semialdehyde aminotransferase; Converts (S)-4-amino-5-oxopentanoate to 5-aminolevulinate during the porphyrin biosynthesis pathway; Derived by automated computational analysis using gene prediction method: Protein Homology.

glutamyl-tRNA reductase; Catalyzes the formation of glutamate-1-semialdehyde from glutamyl-tRNA(Glu) and NADPH; the second step of the pathway is catalyzed by glutamate-1-semialdehyde aminomutase which results in the formation of 5-aminolevulinic acid; functions in porphyrin (tetrapyrroles) biosynthesis; the crystal structure showed a C-terminal dimerization domain that appears to be absent in Chlamydial proteins; Derived by automated computational analysis using gene prediction method: Protein Homology.

uroporphyrinogen-III synthase; Catalyzes cyclization of the linear tetrapyrrole, hydroxymethylbilane, to the macrocyclic uroporphyrinogen III.

Uroporphyrinogen decarboxylase; Catalyzes the formation of coproporphyrinogen from uroporphyrinogen III; Derived by automated computational analysis using gene prediction method: Protein Homology.

Preprotein translocase subunit SecA; Part of the twin-arginine translocation (Tat) system that transports large folded proteins containing a characteristic twin- arginine motif in their signal peptide across membranes. TatA could form the protein-conducting channel of the Tat system.

Preprotein translocase subunit TatB; Part of the twin-arginine translocation (Tat) system that transports large folded proteins containing a characteristic twin- arginine motif in their signal peptide across membranes. Together with TatC, TatB is part of a receptor directly interacting with Tat signal peptides. TatB may form an oligomeric binding site that transiently accommodates folded Tat precursor proteins before their translocation.

Twin-arginine protein translocation system subunit TatC; Part of the twin-arginine translocation (Tat) system that transports large folded proteins containing a characteristic twin- arginine motif in their signal peptide across membranes. Together with TatB, TatC is part of a receptor directly interacting with Tat signal peptides.

Malonyl CoA-ACP transacylase; Derived by automated computational analysis using gene prediction method: Protein Homology.

GTP cyclohydrolase; Derived by automated computational analysis using gene prediction method: Protein Homology; In the N-terminal section; belongs to the DHBP synthase family.
