Gene Information

Name : smpB (P9303_01921)
Accession : YP_001016212.1
Strain : Prochlorococcus marinus MIT 9303
Genome accession: NC_008820
Putative virulence/resistance : Unknown
Product : SsrA-binding protein
Function : -
COG functional category : O : Posttranslational modification, protein turnover, chaperones
COG ID : COG0691
EC number : -
Position : 211205 - 211702 bp
Length : 498 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
