Your Input: | |||||
yeiK | Orf, hypothetical protein; Hydrolyzes cytidine or uridine to ribose and cytosine or uracil, respectively. Has a clear preference for cytidine over uridine. Strictly specific for ribonucleosides; Belongs to the IUNH family. RihB subfamily. (313 aa) | ||||
xseA | Exonuclease VII, large subunit; Bidirectionally degrades single-stranded DNA into large acid- insoluble oligonucleotides, which are then degraded further into small acid-soluble oligonucleotides; Belongs to the XseA family. (456 aa) | ||||
csrA | Carbon storage regulator; A key translational regulator that binds mRNA to regulate translation initiation and/or mRNA stability. Mediates global changes in gene expression, shifting from rapid growth to stress survival by linking envelope stress, the stringent response and the catabolite repression systems. Usually binds in the 5'-UTR; binding at or near the Shine-Dalgarno sequence prevents ribosome-binding, repressing translation, binding elsewhere in the 5'-UTR can activate translation and/or stabilize the mRNA. Its function is antagonized by small RNA(s). (61 aa) | ||||
yggV | Putative ribosomal protein; Pyrophosphatase that catalyzes the hydrolysis of nucleoside triphosphates to their monophosphate derivatives, with a high preference for the non-canonical purine nucleotides XTP (xanthosine triphosphate), dITP (deoxyinosine triphosphate) and ITP. Seems to function as a house-cleaning enzyme that removes non-canonical purine nucleotides from the nucleotide pool, thus preventing their incorporation into DNA/RNA and avoiding chromosomal lesions. Belongs to the HAM1 NTPase family. (197 aa) | ||||
deaD | Inducible ATP-independent RNA helicase; DEAD-box RNA helicase involved in various cellular processes at low temperature, including ribosome biogenesis, mRNA degradation and translation initiation. (646 aa) | ||||
pnp | Polynucleotide phosphorylase; Involved in mRNA degradation. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3'- to 5'- direction. (734 aa) | ||||
dut | Deoxyuridinetriphosphatase; This enzyme is involved in nucleotide metabolism: it produces dUMP, the immediate precursor of thymidine nucleotides and it decreases the intracellular concentration of dUTP so that uracil cannot be incorporated into DNA. (151 aa) | ||||
rph | RNase 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. (238 aa) | ||||
gppA | Guanosine pentaphosphatase; Catalyzes the conversion of pppGpp to ppGpp. Guanosine pentaphosphate (pppGpp) is a cytoplasmic signaling molecule which together with ppGpp controls the 'stringent response', an adaptive process that allows bacteria to respond to amino acid starvation, resulting in the coordinated regulation of numerous cellular activities. (494 aa) | ||||
rhlB | Putative ATP-dependent RNA helicase; DEAD-box RNA helicase involved in RNA degradation. Has RNA- dependent ATPase activity and unwinds double-stranded RNA. Belongs to the DEAD box helicase family. RhlB subfamily. (421 aa) | ||||
dgt | Deoxyguanosine triphosphate triphosphohydrolase; dGTPase preferentially hydrolyzes dGTP over the other canonical NTPs; Belongs to the dGTPase family. Type 1 subfamily. (505 aa) | ||||
rnhB | RNAse HII, degrades RNA of DNA-RNA hybrids; Endonuclease that specifically degrades the RNA of RNA-DNA hybrids; Belongs to the RNase HII family. (198 aa) | ||||
udp | Uridine phosphorylase; Catalyzes the reversible phosphorylytic cleavage of uridine and deoxyuridine to uracil and ribose- or deoxyribose-1-phosphate. The produced molecules are then utilized as carbon and energy sources or in the rescue of pyrimidine bases for nucleotide synthesis. Belongs to the PNP/UDP phosphorylase family. (253 aa) | ||||
rnhA | RNase HI, degrades RNA of DNA-RNA hybrids, participates in DNA replication; Endonuclease that specifically degrades the RNA of RNA-DNA hybrids. (155 aa) | ||||
xseB | Exonuclease VII, small subunit; Bidirectionally degrades single-stranded DNA into large acid- insoluble oligonucleotides, which are then degraded further into small acid-soluble oligonucleotides; Belongs to the XseB family. (80 aa) | ||||
ushA | UDP-sugar hydrolase (5'-nucleotidase); Residues 1 to 550 of 550 are 99.27 pct identical to residues 1 to 550 of 550 from Escherichia coli K-12 Strain MG1655: B0480; Belongs to the 5'-nucleotidase family. (550 aa) | ||||
rne | RNase E, membrane attachment, mRNA turnover, maturation 5S RNA; 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) | ||||
rnb | RNase II, mRNA degradation; Involved in mRNA degradation. Hydrolyzes single-stranded polyribonucleotides processively in the 3' to 5' direction. (644 aa) | ||||

pfs | Orf, hypothetical protein; Catalyzes the irreversible cleavage of the glycosidic bond in both 5'-methylthioadenosine (MTA) and S-adenosylhomocysteine (SAH/AdoHcy) to adenine and the corresponding thioribose, 5'- methylthioribose and S-ribosylhomocysteine, respectively. Also cleaves 5'-deoxyadenosine, a toxic by-product of radical S-adenosylmethionine (SAM) enzymes, into 5-deoxyribose and adenine. Thus, is required for in vivo function of the radical SAM enzymes biotin synthase and lipoic acid synthase, that are inhibited by 5'-deoxyadenosine accumulation. Belongs to the PNP/UDP phospho [...] (232 aa) | ||||
cpdB | 2':3'-cyclic-nucleotide 2'-phosphodiesterase; Residues 1 to 647 of 647 are 99.38 pct identical to residues 1 to 647 of 647 from Escherichia coli K-12 Strain MG1655: B4213; Belongs to the 5'-nucleotidase family. (647 aa) | ||||
