Gene Information

Name : smpB (Shewmr4_2776)
Accession : YP_734904.1
Strain : Shewanella sp. MR-4
Genome accession: NC_008321
Putative virulence/resistance : Unknown
Product : SsrA-binding protein
Function : -
COG functional category : O : Posttranslational modification, protein turnover, chaperones
COG ID : COG0691
EC number : -
Position : 3322658 - 3323149 bp
Length : 492 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
