1. Retinal Pigment Regeneration

   Linked via "porphyropsin"

   Molecular Mechanism: The Rodo-Stabilization Cycle
   The core of RPR involves the complex recycling of retinoids, specifically the conversion of all-trans-retinal back into 11-cis-retinal, which is then re-esterified with the opsin protein to form functional rhodopsin (or porphyropsin in certain deep-sea species). The key enzyme implicated in the isomerization step is the RPE-specific isomerohydrolase, often termed "Isomerase-Zeta" (…
