Abstract:

Bioluminescence occurs in very many different marine organisms. The reaction is an enzyme (luciferase) mediated chemiluminescence in which a substrate (luciferin) is oxidized by molecular oxygen; energy thereby available is conserved in the form of a molecule in an electronically excited (singlet) state which subsequently emits light. The luciferins and luciferases utilized in different organisms may be very different, but all known luciferases may be classed as oxygenases, involving peroxides (in some cases ring peroxides) as intermediates; in some cases electron transfer has been postulated in the terminal steps leading to excitation. The cellular control of bioluminescent reactions involves special mechanisms such as the sequestration of substrate by a binding protein or the accumulation ofa reaction intermediate, and a triggering step, as for example by H+ or Ca++.
