Probable chaperon protein HtpG; Molecular chaperone. Has ATPase activity.

Putative calcium binding protein,40% similarity to TrEMBL;O22845. Has 3 EFh|EF-hand, calcium binding motif;(SMART|SM00054):Many calcium-binding proteins belong to the same evolutionary family and share a type of calcium-binding domain known as the EF-hand. This type of domain consists of a twelve residue loop flanked on both side by a twelve residue alpha-helical domain. In an EF-hand loop the calcium ion is coordinated in a pentagonal bipyramidal configuration. The six residues involved in the binding are in positions 1, 3, 5, 7, 9 and 12; these residues are denoted by X, Y, Z, -Y, -X [...]

DNA-directed DNA polymerase; Poorly processive, error-prone DNA polymerase involved in untargeted mutagenesis. Copies undamaged DNA at stalled replication forks, which arise in vivo from mismatched or misaligned primer ends. These misaligned primers can be extended by PolIV. Exhibits no 3'-5' exonuclease (proofreading) activity. May be involved in translesional synthesis, in conjunction with the beta clamp from PolIII.

Conserved hypothetical protein, has weak homlogs in the Database. TrEMBL;Q88I83(25% Identity). gi|46140644|ref|ZP_00152253.2|, 30% Identity to Dechloromonas aromatica RCB,Nucleotidyltransferase/DNA polymerase involved in DNA repair Has PF00817,impB/mucB/samB family; IPR001126, UMUC_like; These proteins are involved in UV protection.In Escherichia coli, UV and many chemicals appear to cause mutagenesis by a process of translesion synthesis that requires DNA polymerase III and the SOS-regulated proteins UmuD, UmuC and RecA. This machinery allows the replication to continue through DNA le [...]

Aspartate kinase (AK) catalyzes the phosphorylation of aspartate. The product of this reaction can then be used in the biosynthesis of lysine or in the pathway leading to homoserine, which participates in the biosynthesis of threonine, isoleucine and methionine. Similar to trembl|Q8RU02 (80%) and to pir|C83531 (74%). Pfam (PF00696): Amino acid kinase family Pfam (PF01842): two ACT domain; High confidence in function and specificity; Belongs to the aspartokinase family.

Translation initiation factor IF-1; One of the essential components for the initiation of protein synthesis. Stabilizes the binding of IF-2 and IF-3 on the 30S subunit to which N-formylmethionyl-tRNA(fMet) subsequently binds. Helps modulate mRNA selection, yielding the 30S pre-initiation complex (PIC). Upon addition of the 50S ribosomal subunit IF-1, IF-2 and IF-3 are released leaving the mature 70S translation initiation complex.

Chaperone protein DnaK; Acts as a chaperone; Belongs to the heat shock protein 70 family.

Probable chaperone protein; Chaperone involved in the maturation of iron-sulfur cluster- containing proteins. Has a low intrinsic ATPase activity which is markedly stimulated by HscB.
