COMMENTARY

LITERATURE

evolution

Pantoea agglomerans

-

Z-phytoene, synthesized by the all-trans-phytoene synthase is prevalent in higher plants, fungi, algae, and photosynthetic bacteria, while E-phytoene, synthesized by EC 2.5.1.32, often predominates in nonphotosynthetic bacteria. Z-phytoene is the sole product of PSase in a phylogenetically diverse group of organisms, while a smaller subset of organisms have an analogous enzyme that appears to be specific for synthesis of the E isomer

phytoene synthase catalyzes the first pathway specific reaction in the carotenoid biosynthetic pathway and controls flux into the pathway
