Gene Information

Name : smpB (LAF_0371)
Accession : YP_001843187.1
Strain : Lactobacillus fermentum IFO 3956
Genome accession: NC_010610
Putative virulence/resistance : Unknown
Product : SsrA-binding protein
Function : -
COG functional category : O : Posttranslational modification, protein turnover, chaperones
COG ID : COG0691
EC number : -
Position : 445507 - 445980 bp
Length : 474 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
