These data point to a complex mechanism of peroxyl - radical mediated modification of proteins with monomeric ( LYSO ) , dimeric ( G6PD ) , and multimeric ( BLP ) structural organization , which not only results in oxidation of protein side chains but also gives rise to radical - mediated protein cross - links and fragmentation , with Trp species being critical intermediates .
