Protein
Heterocyst inhibition-signaling peptide
Organism
Nostoc sp. (strain PCC 7120 / SAG 25.82 / UTEX 2576)
Length
17 amino acids
Function
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.
