AG3
The protein designated as AG3 (likely a gene identifier in a specific organism, e.g., Arabidopsis thaliana or a plant pathogen, but not a standard universal name) refers to a terpene synthase enzyme classified under EC 4.2.3.119 (for α-pinene synthase) and EC 4.2.3.120 (for β-pinene synthase). Its biological function is to catalyze the cyclization of geranyl diphosphate (GPP) into the monoterpenes (-)-α-pinene and (-)-β-pinene, which are major volatile organic compounds (VOCs) emitted by plants.
These pinenes serve critical ecological roles:
- Plant Defense: Act as anti-herbivore and anti-microbial agents against insects and pathogens.
- Interplant Communication: Signal neighboring plants to activate defense responses.
- Attracting Beneficial Insects: Recruit predators of herbivores (e.g., parasitoid wasps).
Note: The EC numbers 4.2.3.119 and 4.2.3.120 are sometimes used interchangeably or contextually; many pinene synthases produce both isomers, and the distinction in EC numbers may reflect historical classification rather than strict functional separation.

AG3 (pinene synthase, EC 4.2.3.119/120) catalyzes the formation of (-)-α-pinene and (-)-β-pinene from geranyl diphosphate, producing key plant volatile compounds essential for defense against herbivores and pathogens, as well as for interplant communication and ecological signaling.
