Аннотация

Based on silver nanoparticles application, surface-enhanced Raman scattering spectra of D-amino acid oxidase from pig kidney were recorded and analyzed. Spectral parameters characteristic of conformational changes in cofactor flavin adenine dinucleotide during activation of the enzyme by D-amino acids were revealed. It was found that enzyme substrate specificity determines the amount of time from the start of of the conformational changes of flavin adenine dinucleotide until they no longer occur: in the presence of D-alanine, registration of the said conformational changes takes up just a few seconds, while it takes 10 min in the presence of D-serine .
