Mass spectrometric characterization of extensin cross-linkages in arabidopsis tissue culture cell walls
(2020-05)In this work we characterize and identify tyrosine-tyrosine cross-linkages occurring in the Arabidopsis extensin scaffold. Cross-linked extensin peptides were solubilized out of Arabidopsis tissue culture cell walls using ...
