Fig. 3: Comprehensive upregulation of the purine metabolic network in iridophores.
From: Genetic control over biogenic crystal morphogenesis in zebrafish
Schematic representation of the guanine biosynthetic pathway, highlighting differential protein regulation. The selective upregulation of specific enzymes within iridophores emphasizes their distinct roles in guanine biosynthesis and crystal formation. XMP, xanthine monophosphate; GTP, guanine triphosphate.
