Gene Information

Name : smpB (Pnuc_1426)
Accession : YP_001156204.1
Strain : Polynucleobacter necessarius QLW-P1DMWA-1
Genome accession: NC_009379
Putative virulence/resistance : Unknown
Product : SsrA-binding protein
Function : -
COG functional category : O : Posttranslational modification, protein turnover, chaperones
COG ID : COG0691
EC number : -
Position : 1496429 - 1496881 bp
Length : 453 bp
Strand : +
Note : binds to ssrA RNA (tmRNA) and is required for its successful binding to ribosomes; also appears to function in the trans-translation step by promoting accommodation of tmRNA into the ribosomal A site; SmpB protects the tmRNA from RNase R degradation in Ca
