چکیده انگلیسی
Ectoenzymes, or enzymes associated with the cell-surface or periplasmic space, play an important role in organic matter cycling by rendering certain forms of dissolved organic matter bioavailable. Ectoenzyme activities may thereby help meet the nutritional demands of harmful algae such as Prorocentrum minimum. The activities of two ectoenzymes; leucine aminopeptidase and alkaline phosphatase, have been studied in axenic cultures of P. minimum. Leucine aminopeptidase releases non-polar amino acids such as leucine from the N-terminus of polypeptides, whereas alkaline phosphatase is an enzyme that is able to hydrolyze phosphate from phosphomonoesters. P. minimum alkaline phosphatase is the better studied of the two ectoenzymes and its characteristics are reviewed herein. Future research on P. minimum physiology will benefit from a growing suite of tools available for assessing the activity of alkaline phosphatase and other ectoenzymes in field populations and ultimately the work done with P. minimum will be useful for studies of other harmful species.
