But while those enzymes are active, ones that influence the production of isobutanol can't work. (sciencedaily.com)
Single replacement, either Val461 to isoleucine or Ser286 to threonine, increased the Kivd activity significantly, both in vivo and in vitro resulting in increased overall production while isobutanol production was increased more than 3 - methyl -1-butanol production. (solarfuel.se)
Although natural yeast fermentation produces isobutanol, it does so in miniscule amounts. (sciencedaily.com)
