ABSTRACT: This model features the phosphorylation of rat brain neuronal NOS expressed in E. coli or Sf9 cells, which leads to a decrease in Vmax of the phosphorylated enzyme, with little change of both the Km for L-arginine and Kact for CaM. This is based on Hayashi Y. et al. J Biol Chem. (1999) 274(29):20597-602. They report of phosphorylatin being carried out by CaM kinases I alpha, II alpha and IV. The rates used have been obtained from their paper and from other reported data.

Phosphorylation of neuronal nitric-oxide synthase (nNOS) by Ca2+/calmodulin (CaM)-dependent protein kinases (CaM kinases) including CaM kinase Ialpha (CaM-K Ialpha), CaM kinase IIalpha (CaM-K IIalpha), and CaM kinase IV (CaM-K IV), was studied. It was found that purified recombinant nNOS was phosphorylated by CaM-K Ialpha, CaM-K IIalpha, and CaM-K IV at Ser847 in vitro. Replacement of Ser847 with Ala (S847A) prevented phosphorylation by CaM kinases. Phosphorylated recombinant wild-type nNOS at S ...[more]

Project description:Kuznetsov2016(II) - α-syn aggregation kinetics in Parkinson's This theoretical model uses 2-step Finke-Watzky (FW) kinetics todescribe the production, misfolding, aggregation, transport and degradation of α-syn that may lead to Parkinson's Disease (PD). Deregulated α-syn degradation is predicted to be crucialfor PD pathogenesis. This model is described in the article: What can trigger the onset of Parkinson's disease - A modeling study based on a compartmental model of α-synuclein transport and aggregation in neurons. Kuznetsov IA, Kuznetsov AV. Math Biosci 2016 Aug; 278: 22-29 Abstract: The aim of this paper is to develop a minimal model describing events leading to the onset of Parkinson's disease (PD). The model accounts for α-synuclein (α-syn) production in the soma, transport toward the synapse, misfolding, and aggregation. The production and aggregation of polymeric α-syn is simulated using a minimalistic 2-step Finke-Watzky model. We utilized the developed model to analyze what changes in a healthy neuron are likely to lead to the onset of α-syn aggregation. We checked the effects of interruption of α-syn transport toward the synapse, entry of misfolded (infectious) α-syn into the somatic and synaptic compartments, increasing the rate of α-syn synthesis in the soma, and failure of α-syn degradation machinery. Our model suggests that failure of α-syn degradation machinery is probably the most likely cause for the onset of α-syn aggregation leading to PD.
