Uptake of adenine by purine permeases of Coffea canephora [PDF]

Bioscience, Biotechnology, and Biochemistry, 2019
ABSTRACT Purine permeases (PUPs) mediate the proton-coupled uptake of nucleotide bases and their derivatives into cytosol. PUPs facilitate uptake of adenine, cytokinins and nicotine. Caffeine, a purine alkaloid derived from xanthosine, occurs in only a few eudicot species, including coffee, cacao, and tea.

Beverages of Coffee and Phytochemicals Present in Coffea arabica and Coffea canephora – A Review

OUSL Journal, 2023
Coffee plant which belongs to Rubiaceae family, generally grows along the equator in tropical and subtropical areas. The generic name, coffee, covers about 100 species of plants, but the two main species used for making beverages are called Coffea arabica (Arabica, accounting for 60-70% of the world’s production) and Coffea canephora (Robusta).
