Gene Information

Name : smpB (Sala_1730)
Accession : YP_616776.1
Strain : Sphingopyxis alaskensis RB2256
Genome accession: NC_008048
Putative virulence/resistance : Unknown
Product : SsrA-binding protein
Function : -
COG functional category : O : Posttranslational modification, protein turnover, chaperones
COG ID : COG0691
EC number : -
Position : 1821322 - 1821807 bp
Length : 486 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
