Gel-filtration of glyceraldehyde-3-phosphate dehydrogenase from Anabaena variabilis indicates a mol. wt. of 200,000-300,000, which is significantly greater than previously reported for this enzyme from other sources. Reaction rates in the presence NAD of and NADP suggest that one enzyme only is oper
Two kinds of cultures were raised from clones of Anabaena doliolum surviving on selective medium following exposure of spores to ultraviolet radiation. The pigments of these cultures h~ve been characterized with respect to those of controls.
## Abstract Effects of UV radiation on the morphogenesis of __Anabaena doliolum__ are described. After irradiation the frequencies of the 2nd and 3rd cells in 4βcelled filaments differentiating into a heterocyst increase markedly. The spatial relations between successive heterocysts of the series i
