Gene Information

Name : smpB (BUAPTUC7_251)
Accession : YP_002468561.1
Strain : Buchnera aphidicola Tuc7
Genome accession: NC_011834
Putative virulence/resistance : Unknown
Product : SsrA-binding protein
Function : -
COG functional category : O : Posttranslational modification, protein turnover, chaperones
COG ID : COG0691
EC number : -
Position : 281529 - 282017 bp
Length : 489 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
