O52748

- PATS_NOSS1

UniProt

O52748 - PATS_NOSS1

Protein

Heterocyst inhibition-signaling peptide

Gene

patS

Organism
Nostoc sp. (strain PCC 7120 / UTEX 2576)
Status
Reviewed - Annotation score: 2 out of 5- Experimental evidence at protein leveli
  1. 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
