Pacman percolation: a model for enzyme gel degradation
نویسندگان
چکیده
We study a model for the gel degradation by an enzyme, where the gel is schematized as a cubic lattice, and the enzyme as a random walker, that cuts the bonds over which it passes. The model undergoes a (reverse) percolation transition, which for low density of enzymes falls in a universality class different from random percolation. In particular we have measured a gel fraction critical exponent β = 1.0± 0.1, in excellent agreement with experiments made on the real system.

The 5'-3' exoribonuclease Pacman is required for normal male fertility and is dynamically localized in cytoplasmic particles in Drosophila testis cells.
The exoribonuclease Xrn1 is widely recognised as a key component in the 5'-3' RNA degradation pathway. This enzyme is highly conserved between yeast and humans and is known to be involved in RNA interference and degradation of microRNAs as well as RNA turnover. In yeast and human tissue culture cells, Xrn1 has been shown to be a component of P-bodies (processing bodies), dynamic cytoplasmic gra...
متن کاملA model for modified electrode with carbon nanotube composites using percolation theory in fractal space
We introduce a model for prediction the behavior of electrodes which modified withcarbon nanotubes in a polymer medium. These kinds of polymer composites aredeveloped in recent years, and experimental data for its percolation threshold isavailable. We construct a model based on percolation theory and fractal dimensionsand using experimental percolation threshold for calculating the moments of c...
متن کاملXrn1/Pacman affects apoptosis and regulates expression of hid and reaper
Programmed cell death, or apoptosis, is a highly conserved cellular process that is crucial for tissue homeostasis under normal development as well as environmental stress. Misregulation of apoptosis is linked to many developmental defects and diseases such as tumour formation, autoimmune diseases and neurological disorders. In this paper, we show a novel role for the exoribonuclease Pacman/Xrn...
متن کاملIncorporation of r-Amylase Enzyme and a Bioactive Filler into Hydrophilic, Partially Degradable, and Bioactive Cements (HDBCs) as a New Approach To Tailor Simultaneously Their Degradation and Bioactive Behavior
Hydrophilic, partially degradable, and bioactive cements (HDBCs) are starch-containing cements intended to degrade partially in the human body and, in so doing, allow for bone ingrowth inside the pores formed during degradation. Therefore, the study of degradation and bioactivity behavior was performed to assess the suitability of the current HDBCs formulations to achieve those aims. The degrad...
متن کاملComposite nanolayer photocatalyst-biocatalyst Rhodococcus erythropolis R1 for desulfurization of dibenzothiophene
A nanolayer of composite and Rhodococcus erythropolis biocatalyst was studied for the first time for desulfurization of dibenzothiophene as a model sulfur compound and its performance was compared with that of composite and R. erythropolis alone. The nanolayer of composite was synthesized by sol-gel method from ferrous oxalate and zinc oxalate precursors coated on glass by spin coating techniqu...
