1 | REDUCTION OF OXIDATED METHIONINE PEPTIDES FOR MASS SPECTROMETRY | US15360662 | 2016-11-23 | US20170152541A1 | 2017-06-01 | Michael Sweredoski; Annie Moradian; Tanya R. Yakushi; Sonja Hess; Roxana Eggleston-Rangel |
A method for preparing a methionine-containing peptide or protein for analysis by mass spectrometry includes incubating the methionine-containing peptide or protein with a heterologous methionine sulfoxide reductase A (MsrA), MsrB, or MsrAB enzyme resulting in the reduction of oxidized methionine-containing peptides or proteins. |
