In N2-fixing cyanobacteria the reduction of N2 to NH3
with the production of molecular hydrogen (H2), which
consumed by an uptake hydrogenase, an enzyme that is
almost all the diazotrophic cyanobacteria. The
cellular and sub-
cellular localization of the cyanobacterial uptake
remains unclear, and the previously available data
focuses mainly on
In this work the localization of the uptake
hydrogenase in Lyngbya
majuscula CCAP 1446/4, a non-heterocystous
investigated. The data obtained revealed higher
associated with the thylakoid membranes of L. majuscula.
Additionally, a comparative analysis was performed
unicellular - Gloeothece sp. ATCC 27152, and two
strains - Nostoc sp. PCC 7120 and Nostoc punctiforme
No labelling was found on the vegetative cells of
Nostoc sp. PCC
7120, in contrast with the situation in N.
punctiforme, in which
labelling was detected in both vegetative cells and
The results presented in this work will contribute to
understanding of the field of H2 metabolism in
