Researchers provide new insights on the photoconversion mechanism of phytochromes. Dec 17, 2024. Webphytochrome chromoproteins exist in two isomeric forms, inactive Pr and active Pfr, that absorb in the red (R) (peak 660 nm) and far-red (FR) light (peak 730 nm), respectively. R light drives photoconversion from Pr to Pfr, while FR light reverses this process. This R/FR reversibility allows phytochromes to operate
