Electron transport complex, RnfABCDGE type, B subunit; Part of a membrane-bound complex that couples electron transfer with translocation of ions across the membrane. Belongs to the 4Fe4S bacterial-type ferredoxin family. RnfB subfamily.

Polynucleotide adenylyltransferase/metal dependent phosphohydrolase; Catalyzes the addition and repair of the essential 3'- terminal CCA sequence in tRNAs without using a nucleic acid template. Adds these three nucleotides in the order of C, C, and A to the tRNA nucleotide-73, using CTP and ATP as substrates and producing inorganic pyrophosphate. Also shows phosphatase, 2'-nucleotidase and 2',3'-cyclic phosphodiesterase activities. These phosphohydrolase activities are probably involved in the repair of the tRNA 3'-CCA terminus degraded by intracellular RNases.

SsrA-binding protein; Required for rescue of stalled ribosomes mediated by trans- translation. Binds to transfer-messenger RNA (tmRNA), required for stable association of tmRNA with ribosomes. tmRNA and SmpB together mimic tRNA shape, replacing the anticodon stem-loop with SmpB. tmRNA is encoded by the ssrA gene; the 2 termini fold to resemble tRNA(Ala) and it encodes a 'tag peptide', a short internal open reading frame. During trans-translation Ala-aminoacylated tmRNA acts like a tRNA, entering the A-site of stalled ribosomes, displacing the stalled mRNA. The ribosome then switches to [...]

PFAM: Stringent starvation protein B; KEGG: bxe:Bxe_A0418 ClpXP protease specificity-enhancing factor.

Succinyl-diaminopimelate desuccinylase; Catalyzes the hydrolysis of N-succinyl-L,L-diaminopimelic acid (SDAP), forming succinate and LL-2,6-diaminoheptanedioate (DAP), an intermediate involved in the bacterial biosynthesis of lysine and meso-diaminopimelic acid, an essential component of bacterial cell walls; Belongs to the peptidase M20A family. DapE subfamily.

KEGG: bpy:Bphyt_2914 50S ribosomal protein L32; TIGRFAM: ribosomal protein L32; PFAM: ribosomal L32p protein; Belongs to the bacterial ribosomal protein bL32 family.

SmpA/OmlA domain-containing protein; Part of the outer membrane protein assembly complex, which is involved in assembly and insertion of beta-barrel proteins into the outer membrane.

Septum formation initiator; Essential cell division protein. May link together the upstream cell division proteins, which are predominantly cytoplasmic, with the downstream cell division proteins, which are predominantly periplasmic.

PFAM: protein of unknown function YGGT; KEGG: bxe:Bxe_A0880 hypothetical protein.
