patS | Heterocyst-inhibiting signaling peptide; 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. (17 aa) | ||||
petE | Plastocyanin precursor; Participates in electron transfer between P700 and the cytochrome b6-f complex in photosystem I. (139 aa) | ||||
all1175 | ORF_ID:all1175; hypothetical protein. (880 aa) | ||||
hetR | Heterocyst differentiation protein; Controls heterocyst differentiation. Has both a protease and a DNA-binding activity. Binds the promoter regions of hetR, hepA and patS. (299 aa) | ||||
all2874 | Two-component response regulator; ORF_ID:all2874. (330 aa) | ||||
hetN | Ketoacyl reductase; May be involved in repressing heterocyst differentiation and may be essential for preventing all vegetative cells from differentiating. (287 aa) |
