Baker's yeast showed periodical changes in cysteine (CyH) desulfhydration activity with cell growth, and the crude extract from young pantothenate-deficient (PaA-) cells had 1.6 times higher activity than that of pantothenate-sufficient (PaA+) cells of the same growth phase. PaA- cells were also stronger in sulfite reductase activity as examined in 0.6M phosphate buffer. PaA- cells were thus endowed with H2S producibility, although the yeast had more intensive CyH synthetase activity than CyH… CONTINUE READING
