Gene Information

Name : smpB (H650_08990)
Accession : YP_008107624.1
Strain : Enterobacter sp. R4-368
Genome accession: NC_021500
Putative virulence/resistance : Unknown
Product : single-stranded DNA-binding protein
Function : -
COG functional category : -
COG ID : -
EC number : -
Position : 1745879 - 1746361 bp
Length : 483 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
