A study on phosphate metabolism in Undaria cells
Undaria 세포의 인산대사에 관한 연구
Abstract
1.Each cells homogenized from Undaria were reacted in reaction micture to persue the phosphate metabolism in Undaria cell. Aliquots of the cells were taken out at the begin-ning and at intervals during the reaction, and analyzed for the content of total-P in various fractions of the cell constituents. 2.The P-contents in fraction of polyphosphate "B" decreased remarkably, while that in fraction of RNA polyphosphate "C" showed slow increase. 3.As well as in Chlorella cells, inorganic phosphates in DNA-P, protein-P, and lipid-P were transferred from polyphosphate, RNA-P turnovered from inorganic phosphate that is in cytoplasm, and RNA polyphosphate complex from polyphosphate, and it was suggested that inorganic phosphates in polyphosphate "B" could transformed into polyphosphate "A" & "C", and polyphosphate "C" into polyphosphate "A".
