| | dnaB | Putative replicative DNA helicase; Participates in initiation and elongation during chromosome replication; it exhibits DNA-dependent ATPase activity and contains distinct active sites for ATP binding, DNA binding, and interaction with DnaC protein, primase, and other prepriming proteins. (471 aa) |
| | hupA | DNA-binding protein HU-alpha; Histone-like DNA-binding protein which is capable of wrapping DNA to stabilize it, and thus to prevent its denaturation under extreme environmental conditions; Belongs to the bacterial histone-like protein family. (90 aa) |
| | murB | UDP-N-acetylenolpyruvoylglucosamine reductase; Cell wall formation; Belongs to the MurB family. (342 aa) |

| | priA | Primosomal protein N; Involved in the restart of stalled replication forks. Recognizes and binds the arrested nascent DNA chain at stalled replication forks. It can open the DNA duplex, via its helicase activity, and promote assembly of the primosome and loading of the major replicative helicase DnaB onto DNA; Belongs to the helicase family. PriA subfamily. (732 aa) |
| | ftsN | Essential cell division protein; Essential cell division protein that activates septal peptidoglycan synthesis and constriction of the cell. Acts on both sides of the membrane, via interaction with FtsA in the cytoplasm and interaction with the FtsQBL complex in the periplasm. These interactions may induce a conformational switch in both FtsA and FtsQBL, leading to septal peptidoglycan synthesis by FtsI and associated synthases. (324 aa) |
| | yiiU | Putative cytoplasmic protein; Non-essential, abundant cell division factor that is required for proper Z-ring formation. It is recruited early to the divisome by direct interaction with FtsZ, stimulating Z-ring assembly and thereby promoting cell division earlier in the cell cycle. Its recruitment to the Z-ring requires functional FtsA or ZipA. (79 aa) |
| | typA | GTP-binding elongation factor family protein; A 50S ribosomal subunit assembly protein with GTPase activity, required for 50S subunit assembly at low temperatures, may also play a role in translation. Binds GTP and analogs. Binds the 70S ribosome between the 30S and 50S subunits, in a similar position as ribosome-bound EF-G; it contacts a number of ribosomal proteins, both rRNAs and the A-site tRNA (By similarity). A ribosome-stimulated GTPase, GTPase activity increases 4 fold in the presence of 70S ribosomes. Bind to 70S ribosomes in the presence of GTP or its non- hydrolyzable analog [...] (607 aa) |
| | yihA | Putative GTPase involved in coordination of cell cycle; Necessary for normal cell division and for the maintenance of normal septation; Belongs to the TRAFAC class TrmE-Era-EngA-EngB-Septin-like GTPase superfamily. EngB GTPase family. (210 aa) |
| | recQ | ATP-dependent DNA helicase; Involved in the RecF recombination pathway; its gene expression is under the regulation of the SOS system. It is a DNA helicase; Belongs to the helicase family. RecQ subfamily. (615 aa) |
| | uvrD | DNA-dependent ATPase I and helicase II; Has both ATPase and helicase activities. Unwinds DNA duplexes with 3' to 5' polarity with respect to the bound strand and initiates unwinding most effectively when a single-stranded region is present. Involved in the post-incision events of nucleotide excision repair and methyl-directed mismatch repair; Belongs to the helicase family. UvrD subfamily. (720 aa) |
| | cyaY | Putative frataxin family transport protein; Involved in iron-sulfur (Fe-S) cluster assembly. May act as a regulator of Fe-S biogenesis. (106 aa) |
| | rfe | Undecaprenyl-phosphate N-acetylglucosaminyltransferase; Catalyzes the transfer of the GlcNAc-1-phosphate moiety from UDP-GlcNAc onto the carrier lipid undecaprenyl phosphate (C55-P), yielding GlcNAc-pyrophosphoryl-undecaprenyl (GlcNAc-PP-C55). Belongs to the glycosyltransferase 4 family. WecA subfamily. (367 aa) |
| | rep | Rep helicase; Rep helicase is a single-stranded DNA-dependent ATPase involved in DNA replication; it can initiate unwinding at a nick in the DNA. It binds to the single-stranded DNA and acts in a progressive fashion along the DNA in the 3' to 5' direction. (674 aa) |
| | glmU | N-acetyl glucosamine-1-phosphate uridyltransferase; Catalyzes the last two sequential reactions in the de novo biosynthetic pathway for UDP-N-acetylglucosamine (UDP-GlcNAc). The C- terminal domain catalyzes the transfer of acetyl group from acetyl coenzyme A to glucosamine-1-phosphate (GlcN-1-P) to produce N- acetylglucosamine-1-phosphate (GlcNAc-1-P), which is converted into UDP-GlcNAc by the transfer of uridine 5-monophosphate (from uridine 5- triphosphate), a reaction catalyzed by the N-terminal domain. In the C-terminal section; belongs to the transferase hexapeptide repeat family. (456 aa) |
