Description
Summary:Dataset: ARK27-3: Bulk MCA hydrolysis rates This dataset includes peptidase activities measured in bulk (not filter-fractionated) seawater. Links to archived CTD data are also provided. Five substrates linked to a 7-amido-4-methyl coumarin (MCA) fluorophore, one amino acid – leucine – and four oligopeptides – the chymotrypsin substrates alanine-alanine-phenylalanine (AAF) and alanine-alanine-proline-phenylalanine (AAPF), and the trypsin substrates glutamine-alanine-arginine (QAR) and glutamic acid-gylcine-arginine (EGR) – were used to measure exo- and endo-acting peptidase activities, respectively. For a complete list of measurements, refer to the full dataset description in the supplemental file 'Dataset_description.pdf'.
