| | btuD | Vitamin B12 import ATP-binding protein BtuD; Part of the ABC transporter complex BtuCDF involved in vitamin B12 import. Responsible for energy coupling to the transport system. (249 aa) |
| | btuC | Vitamin B12 import system permease protein btuC; Part of the ABC transporter complex BtuCDF involved in vitamin B12 import. Involved in the translocation of the substrate across the membrane. (326 aa) |
| | sppA | Protease 4; Identified by match to protein family HMM PF01343; match to protein family HMM TIGR00705; match to protein family HMM TIGR00706. (618 aa) |
| | yobD | Conserved hypothetical protein; Identified by match to protein family HMM PF06173. (152 aa) |
| | mntP | Putative membrane protein; Probably functions as a manganese efflux pump. Belongs to the MntP (TC 9.B.29) family. (188 aa) |
| | mgrB | Putative lipoprotein; PhoP-regulated transcription is redox-sensitive, being activated when the periplasm becomes more reducing. MgrB acts between DsbA/DsbB and PhoP/PhoQ in this pathway. Represses PhoP/PhoQ signaling, possibly by binding to the periplasmic domain of PhoQ, altering its activity and that of downstream effector PhoP. (47 aa) |
| | htpX | M48B family peptidase; Identified by match to protein family HMM PF01435; match to protein family HMM PF06509; Belongs to the peptidase M48B family. (293 aa) |
| | torY | Trimethylamine N-oxide reductase III, c-type cytochrome subunit TorY; Identified by similarity to SP:P52005; match to protein family HMM PF03264; Belongs to the TorC/TorY family. (366 aa) |
| | lolD | Lipoprotein releasing system, ATP-binding protein; Part of the ABC transporter complex LolCDE involved in the translocation of mature outer membrane-directed lipoproteins, from the inner membrane to the periplasmic chaperone, LolA. Responsible for the formation of the LolA-lipoprotein complex in an ATP-dependent manner. (233 aa) |
| | mltG | Conserved hypothetical protein; Functions as a peptidoglycan terminase that cleaves nascent peptidoglycan strands endolytically to terminate their elongation. (340 aa) |
| | rne | Ribonuclease E; Endoribonuclease that plays a central role in RNA processing and decay. Required for the maturation of 5S and 16S rRNAs and the majority of tRNAs. Also involved in the degradation of most mRNAs. Belongs to the RNase E/G family. RNase E subfamily. (1061 aa) |
