Gene Information

Name : smpB (Synpcc7942_1795)
Accession : YP_400812.1
Strain : Synechococcus elongatus PCC 7942
Genome accession: NC_007604
Putative virulence/resistance : Unknown
Product : SsrA-binding protein
Function : -
COG functional category : O : Posttranslational modification, protein turnover, chaperones
COG ID : COG0691
EC number : -
Position : 1865979 - 1866443 bp
Length : 465 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
