摘要: Abstract The inhibition of sulfhydryl enzymes by a red quinonoid compound isolated from sporulating mushrooms was reported elsewhere. A precursor which is enzymatically converted to the quinone also described, and identified as γ-glutaminyl-4-hydroxybenzene. itself extremely unstable under variety conditions. Acetylated benzoylated derivatives have been prepared analyzed infrared spectroscopy. data indicate that γ-glutaminyl-3,4-benzoquinone. An enzyme capable converting has purified; this exhibits tyrosinase activity, in accord with suggested structure quinone.
