Heterocyst inhibition-signaling peptide

Gene

patS

Organism
Nostoc sp. (strain PCC 7120 / SAG 25.82 / UTEX 2576)
Status
Reviewed-Annotation score: Annotation score: 2 out of 5-Experimental evidence at protein leveli

Functioni

Inhibits heterocyst differentiation. Seems to control heterocyst pattern formation through intercellular signaling mechanisms. In Anabaena filaments every 10th vegetative cell terminally differentiates into a heterocyst specialized for nitrogen fixation. Seems to inhibit the formation of adjacent heterocysts. Inhibits the DNA-binding of HetR.3 Publications

Similar proteinsi

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.
