28271633-3	2017	The oxidation of tyrosine by tyrosinase in the presence of cysteine forms cysteinyldopa isomers, which are further oxidized to give rise to pheomelanin via benzothiazine intermediates.	Cysteine	59-67	tyrosinase	Homo sapiens	29-39	
28271633-6	2017	We found that pheomelanin production either from dopa or tyrosine in the presence of cysteine by tyrosinase was greatest at pH values of 5.8-6.3, while eumelanin production was suppressed at pH 5.8.	Cysteine	85-93	tyrosinase	Homo sapiens	97-107
