M. Kuse et al., 7,8-dihydropterin-6-carboxylic acid as light emitter of luminous millipede, Luminodesmus sequoiae, BIOORG MED, 11(8), 2001, pp. 1037-1040
A luminous millipede, Luminodesmus sequoiae, emits light centered at a wave
length of 500 nm. To determine the light emitter of this bioluminescent sys
tem. fluorescent compounds were isolated from pulverized cuticles. NMR and
MS spectra of these compounds showed them to be pterin derivatives. Further
more, proton/deuterium (HD) exchange experiments by ESI-Q-TOF-MS and -MS/MS
measurements have proved to be a powerful tool for elucidating these heter
oaromatic compounds. Finally? we have concluded that 7,8-dihydropterin-6-ca
rboxylic acid. a new natural product. is the light emitter of Liminodesrmus
bioluminescence. (C) 2001 Elsevier Science Ltd. All rights reserved.
