procollagen-proline 4-dioxygenase complex
procollagen-proline, 2-oxoglutarate-4-dioxygenase complex
protein complex that catalyzes the formation of procollagen trans-4-hydroxy-L-proline and succinate from procollagen L-proline and 2-oxoglutarate, requiring Fe2+ and ascorbate
endoplasmic reticulum protein-containing complex
