Miscellaneousi

Miscellaneous

Unlike the other members of the SMR family, SugE exhibits a narrow specificity for a very specific class of compounds.

Caution

Was originally (PubMed:8096175) thought to suppress a groEL mutation and mimic the effect of groE overexpression. This was later shown (PubMed:11948170) to be probably due to an artifact.2 Publications

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
