| hetF | Heterocyst differentiation protein; ORF_ID:alr3546; hetF gene product. (779 aa) | ||||
| psbA | Photosystem II protein D1; Photosystem II (PSII) is a light-driven water:plastoquinone oxidoreductase that uses light energy to abstract electrons from H(2)O, generating O(2) and a proton gradient subsequently used for ATP formation. It consists of a core antenna complex that captures photons, and an electron transfer chain that converts photonic excitation into a charge separation. The D1/D2 (PsbA/PsbA) reaction center heterodimer binds P680, the primary electron donor of PSII as well as several subsequent electron acceptors. (360 aa) | ||||
| hrcA | Heat-inducible transcriptional repressor; Negative regulator of class I heat shock genes (grpE-dnaK- dnaJ and groELS operons). Prevents heat-shock induction of these operons. (365 aa) | ||||
| ntcA | Nitrogen-responsive regulatory protein; Required for full expression of proteins subject to ammonium repression. Transcriptional activator of genes subject to nitrogen control. (223 aa) | ||||
| all5184 | Mg2+ transport protein; Acts as a magnesium transporter. (466 aa) | ||||
| all5265 | DNA gyrase B subunit; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to modulate DNA topology and maintain chromosomes in an underwound state. Negative supercoiling favors strand separation, and DNA replication, transcription, recombination and repair, all of which involve strand separation. Also able to catalyze the interconversion of other topological isomers of dsDNA rings, including catenanes and knotted rings. Type II topoisomerases break and join 2 DNA strands simultaneously in an ATP-dependent manner. (645 aa) | ||||
| hetN | Ketoacyl reductase; May be involved in repressing heterocyst differentiation and may be essential for preventing all vegetative cells from differentiating. (287 aa) | ||||
| hepA | ATP-binding protein; Acts early in the process of morphological differentiation of heterocysts. (607 aa) | ||||
| fdxB | Ferredoxin; Ferredoxins are iron-sulfur proteins that transfer electrons in a wide variety of metabolic reactions. (97 aa) | ||||
| patB | Transcriptional regulator; ORF_ID:all2512; patB gene product. (529 aa) | ||||
| pilT | Twitching motility protein; ORF_ID:all2443; pilT gene product. (372 aa) | ||||
| pilT-2 | Twitching motility protein; ORF_ID:all3329; pilT gene product. (432 aa) | ||||
| nlpD | Lipoprotein; ORF_ID:asl2362; nlpD gene product. (77 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) | ||||
| glnA | Glutamate--ammonia ligase; Involved in nitrogen metabolism via ammonium assimilation. Catalyzes the ATP-dependent biosynthesis of glutamine from glutamate and ammonia; Belongs to the glutamine synthetase family. (474 aa) | ||||
| 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) | ||||
| dnaA | Chromosomal replication initiator protein; Plays an important role in the initiation and regulation of chromosomal replication. Binds to the origin of replication; it binds specifically double-stranded DNA at a 9 bp consensus (dnaA box): 5'- TTATC[CA]A[CA]A-3'. DnaA binds to ATP and to acidic phospholipids. (459 aa) | ||||
| alr0094 | Glutamate racemase; Provides the (R)-glutamate required for cell wall biosynthesis. (292 aa) | ||||
| alr0101 | ORF_ID:alr0101; unknown protein. (258 aa) | ||||
| alr0487 | Cell division protein SepF; Cell division protein that is part of the divisome complex and is recruited early to the Z-ring. Probably stimulates Z-ring formation, perhaps through the cross-linking of FtsZ protofilaments. Its function overlaps with FtsA. (198 aa) | ||||
| patA | Two-component response regulator, heterocyst pattern formation protein; Controls heterocyst pattern formation. Required for the differentiation of intercalary heterocysts but not for terminal heterocysts. (379 aa) | ||||

| nifW | Nitrogen fixation protein; May protect the nitrogenase Fe-Mo protein from oxidative damage; Belongs to the NifW family. (105 aa) | ||||
| nifB | Nitrogen fixation protein; Involved in the biosynthesis of the iron-molybdenum cofactor (FeMo-co or M-cluster) found in the dinitrogenase enzyme of the nitrogenase complex in nitrogen-fixing microorganisms. NifB catalyzes the crucial step of radical SAM-dependent carbide insertion that occurs concomitant with the insertion of a 9th sulfur and the rearrangement/coupling of two [4Fe-4S] clusters into a [8Fe-9S-C] cluster, the precursor to the M-cluster.

| rbcS | Ribulose 1,5-bisphosphate carboxylase/oxygenase small subunit; RuBisCO catalyzes two reactions: the carboxylation of D- ribulose 1,5-bisphosphate, the primary event in carbon dioxide fixation, as well as the oxidative fragmentation of the pentose substrate.
