✦ Synopsis

Kinetic studies on the NADP-linked glutamate dehydrogenase (GDH) activity in 8 species of marine phytoplankton have been carried out. The pH optima, linearity of reactions, apparent energies of activation, and apparent K m values for NADPH, NH~ and ~-ketoglutarate were determined. Based on these data, an accurate, sensitive enzyme assay procedure is presented which was successfully tested on shipboard during a recent cruise in an upwelling region. Preliminary studies on inhibition and activation of the NADP-linked GDH activity have also been carried out. In addition to NADP-linked GDH activity, NAD-linked GDH activity was discovered in certain species of phytoplankton. The possible physiological roles of NAD-and NADP-linked GDH enzymes are discussed.
