Theobromine 45-56 cytochrome P450 family 2 subfamily E member 1 Homo sapiens 109-115 1302044-5 1992 The most striking finding was that CYP2E1 (the ethanol-inducible form) had major influences upon caffeine metabolism: in particular, it catalysed the formation of theophylline and theobromine from caffeine. Theobromine 180-191 cytochrome P450 family 2 subfamily E member 1 Homo sapiens 35-41
