| Abstract: | Extent of prolyl hydroxylation in newly synthesized viper collagen is decreased at 10 degrees C to approximately 23% of normal on skin and to approximately 57% of normal in bone collagen. At 20 degrees C, prolyl hydroxylation is approximately 50% of normal in skin and normal in bone. At 10 degrees C and 20 degrees C, prolyl hydroxylation is decreased approximately 32% in the skin collagen of carp. In contrast, prolyl hydroxylation is unchanged at 10 and 20 degrees C in bone, scale and lepidotrichia. Prolyl hydroxylation of cartilaginous endoskeleton showed an approximately 25% decrease at 20 degrees C. |
