Protein

Probable GTP-binding protein EngB

Gene

engB

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Necessary for normal cell division and for the maintenance of normal septation. Depletion of this protein leads to a severe reduction in growth rate and to extensive filamentation, with a block beyond the stage of segregation. Essential for bacteria survival.UniRule annotation1 Publication

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.
