* SsrA-binding protein *
************************

A protein  which  orignally  was  called, in Escherichia coli, small protein B
(gene smpB)  binds  specifically  to  the ssrA RNA (tmRNA) and is required for
stable association  of ssrA with ribosomes [1]. It is a hydrophilic protein of
about 145 to 160 amino-acid residues.

As a  signature  pattern,  we  selected  a  conserved region in the N-terminal
section.

-Consensus pattern: [STAC]-G-[LIVM]-x-L-x-G-x-E-[LIVM]-[KQ]-[SA]-[LIVMA]
-Sequences known to belong to this class detected by the pattern: ALL.
-Other sequence(s) detected in Swiss-Prot: NONE.
-Last update: December 2001 / Pattern and text revised.
