1. | ALA3706344 | B | Fluorometric Assay: All measurements were performed with a BioAssay Reader HTS-7000Plus for microplates (Perkin Elmer) at 30C. QC activity was evaluated fluorometrically using H-Gln-beta NA. The samples consisted of 0.2 mM fluorogenic substrate, 0.25 U pyroglutamyl aminopeptidase (Unizyme, Horsholm, Denmark) in 0.2 M Tris/HCl, pH 8.0 containing 20 mM EDTA and an appropriately diluted aliquot of QC in a final volume of 250 ul. Excitation/emission wavelengths were 320/410 nm. The assay reactions were initiated by addition of glutaminyl cyclase. QC activity was determined from a standard curve of beta -naphthylamine under assay conditions. One unit is defined as the amount of QC catalyzing the formation of 1 umol pGlu-beta NA from H-Gln-beta NA per minute under the described conditions. In a second fluorometric assay, QC was activity determined using H-Gln-AMC as substrate. Reactions were carried out at 30C. utilizing the NOVOStar reader for microplates (BMG labtechnologies). | Homo sapiens | 17 | single protein format | BindingDB Database |
