Gene Information

Name : smpB (CYB_1264)
Accession : YP_477502.1
Strain : Synechococcus sp. JA-2-3B'a(2-13)
Genome accession: NC_007776
Putative virulence/resistance : Unknown
Product : SsrA-binding protein
Function : -
COG functional category : O : Posttranslational modification, protein turnover, chaperones
COG ID : COG0691
EC number : -
Position : 1321806 - 1322270 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
