Nitric oxide synthase is induced in sporulation of Physarum polycephalum.
The myxomycete Physarum polycephalum expresses a calcium-independent nitric oxide (NO) synthase (NOS) resembling the inducible NOS isoenzyme in mammals. We have now cloned and sequenced this, the first nonanimal NOS to be identified, showing that it shares < 39% amino acid identity with known NOSs but contains conserved binding motifs for all NOS cofactors. It lacks the sequence insert responsi...
متن کاملCalcium and malate are sporulation-promoting factors of Physarum polycephalum.
Fruiting body formation (sporulation) is a distinctive, irreversible differentiation process in the life cycle of the slime mold Physarum polycephalum. The most important requirement for sporulation of Physarum is a period of starvation, and normally sporulation proceeds in the light. It is shown here that by omitting the liquid sporulation medium and elevating the temperature from 21 to 25 deg...
متن کاملDifferential protein synthesis during sporulation in the slime mold Physarum polycephalum.
The size distribution and synthesis of polypeptide chains and the polysome patterns were studied during sporulation of the slime mold Physarum polycephalum, and were compared with nonsporulating controls. The proteins were divided into a 27,000 x g supernatant (buffer-soluble proteins) and a pellet (buffer-insoluble proteins) while still native. The sodium dodecyl sulfate complexes of the denat...
متن کاملControl of histone gene expression in Physarum polycephalum. I. Protein synthesis during the cell cycle.
Synchronous cultures of Physarum polycephalum were pulsed with [3H]lysine hydrochloride in S and G2 phases of the cell cycle. Plasmodial extracts were separated into nuclear, ribosomal and acid-soluble post-ribosomal cytoplasmic fractions. Core histones could be detected by staining in the nuclear fractions of both S and G2 phases, but were not detected by staining in the cytoplasmic fractions....
متن کاملLogical Modelling of Physarum Polycephalum
In the paper we proposed a novel model of unconventional computing where a structural part of computation is presented by dynamics of Plasmodium of Physarum polycephalum, a large single cell. We sketch a new logical approach combining conventional logic with process calculus to demonstrate how to employ formal methods in design of unconventional computing media presented by Physarum polycephalu...
