Fatty oxidation complex, alpha subunit; Catalyzes the formation of a hydroxyacyl-CoA by addition of water on enoyl-CoA. Also exhibits 3-hydroxyacyl-CoA epimerase and 3- hydroxyacyl-CoA dehydrogenase activities; In the N-terminal section; belongs to the enoyl-CoA hydratase/isomerase family.

Fatty oxidation complex, alpha subunit; Involved in the aerobic and anaerobic degradation of long- chain fatty acids via beta-oxidation cycle. Catalyzes the formation of 3-oxoacyl-CoA from enoyl-CoA via L-3-hydroxyacyl-CoA. It can also use D-3-hydroxyacyl-CoA and cis-3-enoyl-CoA as substrate. In the C-terminal section; belongs to the 3-hydroxyacyl-CoA dehydrogenase family.

Succinate dehydrogenase, hydrophobic membrane anchor protein; Membrane-anchoring subunit of succinate dehydrogenase (SDH).

Sensor histidine kinase; Similar to GP:2808665; identified by sequence similarity; putative.

Sodium/glutamate symporter; Catalyzes the sodium-dependent transport of glutamate. Belongs to the glutamate:Na(+) symporter (ESS) (TC 2.A.27) family.

Indole-3-glycerol phosphate synthase/phosphoribosylanthranilate isomerase; Bifunctional enzyme that catalyzes two sequential steps of tryptophan biosynthetic pathway. The first reaction is catalyzed by the isomerase, coded by the TrpF domain; the second reaction is catalyzed by the synthase, coded by the TrpC domain (By similarity).

Tryptophan synthase, alpha subunit; The alpha subunit is responsible for the aldol cleavage of indoleglycerol phosphate to indole and glyceraldehyde 3-phosphate. Belongs to the TrpA family.

Tryptophan synthase, beta subunit; The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine.

5-methyltetrahydrofolate--homocysteine methyltransferase; 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).
