Gene Information

Name : smpB (Smal_1590)
Accession : YP_002027978.1
Strain : Stenotrophomonas maltophilia R551-3
Genome accession: NC_011071
Putative virulence/resistance : Unknown
Product : SsrA-binding protein
Function : -
COG functional category : O : Posttranslational modification, protein turnover, chaperones
COG ID : COG0691
EC number : -
Position : 1788506 - 1789009 bp
Length : 504 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
