Probable 3-mercaptopyruvate sulfurtransferase; Transfers a sulfur ion to cyanide or to other thiol compounds.

Cysteine synthase A; Product name confidence: Class 2 (High similarity to functionally studied protein); Belongs to the cysteine synthase/cystathionine beta- synthase family.

Methionine synthase; Catalyzes the transfer of a methyl group from methyl- cobalamin to homocysteine, yielding enzyme-bound cob(I)alamin and methionine. Subsequently, remethylates the cofactor using methyltetrahydrofolate (By similarity).

Probable cysteine synthase; Product name confidence: Class 3 (Function proposed based on presence of conserved amino acid motif, structural feature or limited sequence similarity to an experimentally studied gene).

5-methyltetrahydropteroyltriglutamate- homocysteine S-methyltransferase; Catalyzes the transfer of a methyl group from 5- methyltetrahydrofolate to homocysteine resulting in methionine formation; Belongs to the vitamin-B12 independent methionine synthase family.

Conserved hypothetical protein; Product name confidence: Class 4 (Homologs of previously reported genes of unknown function, or no similarity to any previously reported sequences).

Thiosulfate:cyanide sulfurtransferase; Catalyzes the sulfur transfer reaction from thiosulfate to cyanide, thus converting cyanide to the less toxic thiocyanate. Contributes to P.aeruginosa survival under cyanogenic conditions, and thus provides the bacterium with a defense mechanism against endogenous cyanide toxicity. Is the main cytoplasmic rhodanese in P.aeruginosa, accounting for 90% of total rhodanese activity.

methionyl-tRNA synthetase; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation.

Branched-chain amino acid transferase; Acts on leucine, isoleucine and valine; Belongs to the class-IV pyridoxal-phosphate-dependent aminotransferase family.
