Preferential binding of S phase proteins to temporally characteristic units of replication in Physarum polycephalum
Synchronous plasmodia of Physarum polycephalum were pulse-labeled with 3H-thymidine in early or late portions of the S-phase, and the binding capacity of the replicated DNA for isochronous S-phase plasmodial proteins assessed by nitrocellulose filter binding assay. Replication units replicating duri...

description | Synchronous plasmodia of Physarum polycephalum were pulse-labeled with 3H-thymidine in early or late portions of the S-phase, and the binding capacity of the replicated DNA for isochronous S-phase plasmodial proteins assessed by nitrocellulose filter binding assay. Replication units replicating during the first one-third of the S-phase preferentially bind cytosol proteins present in plasmodia engaged in early S DNA replication, while late S replicating DNA exhibits a corresponding preferential binding of plasmodial proteins present only in late S plasmodia. Temporally-characteristic nascent replication units were isolated by Hydroxylapatite column chromatography and were found to contain binding sites for isochronous proteins. |
