Free Ribonucleotides of Physarum polycephalum
European Journal of Biochemistry, 1969Free ribonucleotides in plasmodia of Physarum polycephalum at different stages of the synchronous mitotic cycle were determined by anion exchange chromatography. The nucleotide pattern of this myxomycete resembled that obtained from rat liver. The contents of total adenine nucleotides based on protein content were almost identical in both tissues ...

Purine metabolism in microplasmodia of Physarum polycephalum
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1979The uptake and utilization of purine nucleosides and purines in microplasmodia of Physarum polycephalum were investigated. The results revealed a unique pattern, namely that exogenous purine nucleosides are readily taken up and metabolised, while free purine bases are hardly taken up.

Hardware Acceleration of Cellular Automata Physarum polycephalum Model
Parallel Processing Letters, 2015During the past decades, computer science experts were inspired from the study of biological organisms. Moreover, bio-inspired algorithms were produced that many times can give excellent solutions with low computational cost in complex engineering ...

Nuclear matrix proteins of Physarum polycephalum
Molecular Biology Reports, 1986The proteins of nuclear matrix preparations from Physarum polycephalum were compared with analogous mammalian fractions by gel electrophoresis, DNA-binding studies and immunological tests. Polypeptides of 28 and 36 K dalton, which dominate in Physarum preparations, differed from calf thymus matrix proteins in that they were basic and showed low ...

Characterization of the Thymidine Kinase of Physarum polycephalum
The Journal of Biochemistry, 1983Thymidine kinase [ATP: thymidine 5'-phosphotransferase, EC 2.7.1.21] has been purified more than 3,500 fold from microplasmodia of Physarum polycephalum. Properties of the enzyme were determined on preparations purified 1,400 fold. Thymidine was transformed to dTMP while a stoichiometric quantity of ATP was transformed to ADP.

Alkaline phosphatase of Physarum polycephalum is insoluble [PDF]
Archives of Microbiology, 2007 The plasmodia of Physarum polycephalum grow as multinucleated cells in the presence of sufficient humidity and nutriment. Under non-illuminating conditions, stresses such as low temperature or high concentrations of salts transform the plasmodia into spherules whereas dehydration induces sclerotization.

Microplasmodium Dynamics of Physarum Polycephalum
2010The slime mold Physarum polycephalum exhibits well-known oscillations of its vein network, which drive the so-called shuttle streaming of endoplasmic fluid within the veins. These oscillations are already visible in microplasmodia, which are precursors of extended networks.

Thermotaxis in a slime mold, Physarum polycephalum
Behavioral Biology, 1975Physarum polycephalum is thermotactic toward 29 ± 1°C avoiding both higher and lower temperatures. 29°C appears to be a- combined optima for growth and locomotion. It is likely that thermotaxis is a more efficient way of avoiding unfavorable temperature than transforming into spherules.

Ribosomal DNA in spores of Physarum polycephalum
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1978DNA was isolated from plasmodia, spores and newly hatched amoebae of the slime mould Physarum polycephalum. The DNA preparations were fractionated in CsCl gradients and each fraction hybridised to combined 19 S + 26 S rRNA. In all three DNA preparations hybridisation was found to be limited to satellite DNA (rho = 1.714 g/cm3) and at saturation was ...
