Biphasic kinetic behavior of nitrate reductase from heterocystous, nitrogen-fixing cyanobacteria.
Nitrate reductase activity from filamentous, heterocyst-forming cyanobacteria showed a biphasic kinetic behavior with respect to nitrate as the variable substrate. Two kinetic components were detected, the first showing a higher affinity for nitrate (K(m), 0.05-0.25 mm) and a lower catalytic activity and the second showing a lower affinity for nitrate (K(m), 5-25 mm) and a higher (3- to 5-fold)...
متن کاملGlutamine Synthetase from the Nitrogen-fixing Cyanobacteria
Glutamine synthetase has been purified to homogeneity from two N,-fixing cyanobacteria, Anabaena cylindrica and a species of Nostoc (the phycobiont of Peltigera canina). The activities of the A . cylindrica enzyme in the biosynthetic and transferase assays were, respectively, 9-4 and 32 pmol product formed min-l (mg protein)-l; the corresponding values for the Nostoc sp. enzyme were 6.5 and 20....
متن کاملMembrane electrogenesis and sodium transport in filamentous nitrogen-fixing cyanobacteria.
Transport of Na+ and its relationship with membrane potential (delta psi m) was examined in Anabaena L-31 (a fresh water cyanobacterium) and Anabaena torulosa (a brackish water cyanobacterium) which require Na+ for diazotrophic growth. The data on the effect of N,N'-dicyclohexylcarbodiimide indicated that delta psi m was generated by electrogenic proton extrusion predominantly mediated by ATPas...

متن کاملNew Records of Nostocalean Cyanobacteria from Rice Fields in the Golestan Province in North-East of Iran
The algal flora of five stations from paddy-fields of Golestan Province was investigated between October 2006 and September 2007. Eight filamentous heterocystous Nostocacean are recorded here for the first time from paddy fields of iran: Cylindrospermum licheniforme, Cylindrospermum stangnale, Cylindrospermopsis raciborskii, Calothrix ghosei, Gloeotrichia longiarticulata, Aulosira implexa var. ...
