Abstract：
:We have examined the metabolism of phosphate and sulfate groups modifying the P0 protein, the major protein of peripheral nervous system myelin, using an in vitro incubation system. Incorporation of [3H]leucine into the P0 peptide backbone decreased approximately 25-fold between 10 and 90 days of age, a finding reflecting a decreased rate of myelin synthesis in the older animals. In contrast, incorporation of [32P]phosphate into P0 decreased only four- to fivefold, a result indicating that phosphate groups are metabolized independently of the peptide backbone. Developmental decreases in the incorporation of sulfate groups into P0 were similar to those seen for leucine, an observation suggesting that this modifying group is metabolized together with the peptide backbone as a single metabolic entity. The time course of labeling of P0 isolated from the starting homogenate and from myelin was also compared. Results are consistent with sulfation of P0 protein taking place before insertion of newly synthesized P0 into myelin. In contrast, incorporation of phosphate into P0 appears to involve both the newly synthesized pool and the preexisting pool of P0 in myelin. Presumably, entry of phosphate into P0 in myelin involves turnover of preexisting phosphate groups and rephosphorylation by myelin protein kinases. Developmental decreases in the specific activity of P0 phosphate groups in myelin are consistent with the presence of a small, rapidly turning-over pool of phosphorylated P0 (perhaps associated with the axon-myelin interface), which does not increase to the same extent as the marked increase in bulk myelin that occurs during development.
