polihidroxialcanoato
Scope note: Poliésteres microbianos biodegradables que contienen monómeros de hidroxiacilo. Los polihidroxialcanoatos son materiales de reserva de energía y carbono producidos y secuestrados en gránulos citoplasmáticos llamados gránulos de polihidroxialcanoato o PHA por varias arqueas y bacterias y, además, pueden proporcionar un mecanismo de protección a los microorganismos. Son biosintetizados por enzimas microbianas polihidroxialcanoato-sintasas que usan ácidos grasos o enzimas citramalato-sintasa que usan glucosa.

Scope note: Biodegradable microbial polyesters which contain hydroxyacyl monomers. Polyhydroxyalkanoates are carbon and energy reserve materials produced and sequestered in cytoplasmic granules called polyhydroxyalkanoate or PHA granules by various archaea and bacteria and may additionally provide protective mechanism to the microbes. They are biosynthesized by microbial polyhydroxyalkanoate synthase enzymes using fatty acids or citramalate synthase enzymes using glucose.
