2019/10/28
Results of a new NSF-supported study led by researchers at the Woods Hole Oceanographic Institution and Swansea University Medical School increase our knowledge of viruses -- in the sea and on land --...
Proteolytic enzymes in coastal surface seawater: Significant activity of endopeptidases and exopeptidases
Proteolytic enzymes coastal surface seawater endopeptidases exopeptidases
2014/5/9
We assayed proteolytic enzymes in coastal surface seawater using 16 types of fluorogenic substrates, including those for aminopeptidase, trypsin, elastase, and chymotrypsin. Hydrolysis rates were simi...
Photochemical effects on the interaction of enzymes and dissolved organic matter in natural waters
