Putative efflux transporter; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pt: putative transporter.

Putative transcriptional regulator; Represses the expression of the yvmC-cypX operon, which is involved in pulcherriminic acid biosynthesis. Also negatively regulates yvmA, yvnB and its own expression. Positively regulates yisI expression. Acts by binding specifically to a 14-bp palindromic motif, the YvmB box, which is present in the promoter region of the target genes.

Glucose 1-dehydrogenase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the short-chain dehydrogenases/reductases (SDR) family.

Putative oxidoreductase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme; Belongs to the short-chain dehydrogenases/reductases (SDR) family.

Cyclodipeptide synthase; Involved in the biosynthesis of pulcherrimin, a red extracellular pigment. It uses activated amino acids in the form of aminoacyl-tRNAs (aa-tRNAs) as substrates to catalyze the ATP- independent formation of cyclodipeptides which are intermediates in diketopiperazine (DKP) biosynthetic pathways. Catalyzes the formation of cyclo(L-Leu-L-Leu) (cLL) from L-leucyl-tRNA(Leu). Can also incorporate various nonpolar residues, such as L-phenylalanine, L- leucine and methionine, into cyclodipeptides.

cyclo-L-leucyl-L-leucyl dipeptide oxidase; Involved in the biosynthesis of pulcherrimin, a red extracellular pigment. Catalyzes the oxidation of cyclo(L-Leu-L-Leu) (cLL) to yield pulcherriminic acid which forms pulcherrimin via a nonenzymic reaction with Fe(3+). Substrates with small alkyl groups (cAA, cLG, cLP) exhibit weaker binding to CYP134A1, but substrates with larger hydrophobic side chains bind in a similar regime to cLL. Belongs to the cytochrome P450 family.

Spo0A-P phosphatase; Aspartyl-phosphate phosphatase which specifically dephosphorylates the sporulation transcription factor Spo0A-P and negatively regulates the sporulation initiation pathway in order to control the proper timing of sporulation. Belongs to the spo0E family.

Putative integral inner membrane protein; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pm: putative membrane component.

Aryl-phospho-beta-d-glucosidase; Is able to catalyze the hydrolysis of aryl-phospho-beta-D- glucosides such as 4-methylumbelliferyl-phospho-beta-D-glucopyranoside (MUG-P), phosphoarbutin and phosphosalicin. Is not essential for growth on arbutin and salicin as the sole carbon source. Belongs to the glycosyl hydrolase 1 family.
