Nicotinate-nucleotide--dimethylbenzimidazole phosphoribosyltransferase; Catalyzes the synthesis of alpha-ribazole-5'-phosphate from nicotinate mononucleotide (NAMN) and 5,6-dimethylbenzimidazole (DMB).

Cobinamide kinase/cobinamide phosphate guanylyltransferase; Catalyzes ATP-dependent phosphorylation of adenosylcobinamide and addition of GMP to adenosylcobinamide phosphate.

Cobyric acid synthase; Catalyzes amidations at positions B, D, E, and G on adenosylcobyrinic A,C-diamide. NH(2) groups are provided by glutamine, and one molecule of ATP is hydrogenolyzed for each amidation. Belongs to the CobB/CobQ family. CobQ subfamily.

Succinylglutamate desuccinylase; Transforms N(2)-succinylglutamate into succinate and glutamate; Belongs to the AspA/AstE family. Succinylglutamate desuccinylase subfamily.

Vitamin B12 ABC transporter, permease protein BtuC, putative; Part of the ABC transporter complex BtuCDF involved in vitamin B12 import. Involved in the translocation of the substrate across the membrane.

Vitamin B12 ABC transporter, ATP-binding protein BtuD, putative; Part of the ABC transporter complex BtuCDF involved in vitamin B12 import. Responsible for energy coupling to the transport system.

Conserved hypothetical protein; Identified by Glimmer2; putative.

Ribonuclease PH; Phosphorolytic 3'-5' exoribonuclease that plays an important role in tRNA 3'-end maturation. Removes nucleotide residues following the 3'-CCA terminus of tRNAs; can also add nucleotides to the ends of RNA molecules by using nucleoside diphosphates as substrates, but this may not be physiologically important. Probably plays a role in initiation of 16S rRNA degradation (leading to ribosome degradation) during starvation.

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).
