title: An improved method of light-induced pigmentation.
abstract: An improved procedure was developed whereby a primary light signal can be intensified and made visible by activation of a pre-tyrosinase (pre-phenoloxidase) enzyme [isolated from silkworm (Bombyx mori)] by alpha-chymotrypsin; this activation results from the light-activated conversion of the inactive cis-cinnamoyl-alpha-chymotrypsin.
