Red cell enzyme activities and properties of mutant pyruvate kinase after long-term storage of red cells in liquid nitrogen. 1979

H Fujii, and S Miwa, and Y Ishida, and E Oda, and T Nakatsuji, and Y Miura

After 8 months of storage of normal red cells in liquid nitrogen, red cell enzyme activities were essentially unchanged, except for triose phosphate isomerase which was reduced by about half. Mutant pyruvate kinase (PK), PK Tokyo I, showed no changes in kinetic or electrophoretic properties after 8 months of storage. These findings indicate that red cells stored for a long term in liquid nitrogen can still be used for the study of mutant PK.

UI MeSH Term Description Entries
D007700 Kinetics The rate dynamics in chemical or physical systems.
D009154 Mutation Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations. Mutations
D009584 Nitrogen An element with the atomic symbol N, atomic number 7, and atomic weight [14.00643; 14.00728]. Nitrogen exists as a diatomic gas and makes up about 78% of the earth's atmosphere by volume. It is a constituent of proteins and nucleic acids and found in all living cells.
D011770 Pyruvate Kinase ATP:pyruvate 2-O-phosphotransferase. A phosphotransferase that catalyzes reversibly the phosphorylation of pyruvate to phosphoenolpyruvate in the presence of ATP. It has four isozymes (L, R, M1, and M2). Deficiency of the enzyme results in hemolytic anemia. EC 2.7.1.40.
