The requirements for activity of blue-green algal nitrogenase have been studied. The optimal concentration ranges for ATP and Na~S204 are 2--3 m~ and 4--10 mlYl respectively. A magnesium requirement has been confirmed but the enzyme is not specific for Mg ~+, Co 2+ and Mn 2+ will also support activi
The L-alanine dehydrogenase (ADH) of Anabaena cylindrica has been purified 700-fold. It has a molecular weight of approximately 270,000, has 6 sub-units, each of molecular weight approximately 43,000, and shows activity both in the aminating and deaminating directions. The enzyme is NADH/NAD+ specif
