Resumen:
The majority (>80%) of the Earths surface is exposed to temperatures below 5 °C throughout the year. Cold stress triggers the
production of active oxygen species in the respiratory chain, since it alters the properties of cellular membranes. The isoprenoids are an extremely
diverse group of reduced organic compounds that increase fitness in changing environments. The first step of isoprenoid biosynthesis via mevalonate
is catalyzed by a tiolase II (EC 2.3.19) which condenses two molecules of acetyl CoA to give acetoacetyl CoA.
