| 1.12.99.6 | hydrogenase (acceptor) |
heterocyst |
fusion protein with Green Fluorescent Protein is exlusively detected in heterocysts. The fluorescence in mature heterocysts is localized to several small or fewer large clusters, indicating a specificity of the subcellular localization of the uptake hydrogenase |

| 2.5.1.46 | deoxyhypusine synthase |
heterocyst |
SpeY accumulates in vegetative cells but also at significant levels in heterocysts |
751585 |
| 2.7.7.65 | diguanylate cyclase |
heterocyst |
heterocyst differentiation pathway (upstream of HetR), decreased heterocyst frequency and block of heterocyst differentiation within 4 days in mutant strain depleted for all2874 gene and grown in absence of source of combined nitrogen |
692878 |
| 3.2.1.26 | beta-fructofuranosidase |
heterocyst |
compared to invertase InvA, invertase InvB possesses a much higher catalytic activity. The higher activity may be responsible for the vital role of InvB in heterocyst development and nitrogen fixation |
750547 |
| 3.4.15.6 | cyanophycinase |
heterocyst |
compartmentalized degradation of cyanophycin, with the first step, catalyzed by cyanophycinase, taking place in the heterocysts and the second step, catalyzed by a dipeptidase, taking place mainly in the vegetative cells |
-, 728700 |
| 3.5.3.11 | agmatinase |
heterocyst |
the protein is present at significantly lower levels in heterocysts than in vegetative cells |
-, 734651 |
