Once covered in dense forest, much of the Indonesian landscape has been gradually cleared for permanent fields and settlements as rice cultivation developed over the last 1500 years. In the Philippines, the greatest evidence of rice cultivation since ancient
Arogenate dehydratase hybrida", "Sorghum bicolor"", "and "Oryza sativa"", "which are all considered higher-order plants. "Erwinia herbicola"" and Pseudomonas aeruginosa"" "are known to" "have homologues for cyclohexadienyl dehydratase. Of the plants with ADT homologues, both "Arabidopsis thaliana "and "Petunia hybrida "are known to have paralogues for the gene (six and three, respectively). Arogenate dehydratase Arogenate dehydratase (ADT) (EC 4.2.1.91) is an enzyme that catalyzes the chemical reaction Hence, this enzyme has one substrate, L-arogenate, but 3 products:L-phenylalanine, HO, and CO. Certain forms of the protein have the potential to catalyze a second reaction, L-prephenate → L-phenylpyruvate + HO + CO This enzyme participates
