Membrane-bound Turing patterns.
Motivated by recent observations in biological cells, we study Turing patterns in bounded regions where the nonlinear chemical reactions occur on the boundary and where reagent transport occurs in the bulk. Within a generic model, we formulate the stability problem and discuss the conditions for the occurrence of a Turing instability. By choosing other model parameters to be unequal, we find th...
متن کاملStability of membrane bound reactions.
We present a novel approach to the dynamics of reactions of diffusing chemical species with species fixed in space, e.g., by binding to a membrane. The nondiffusing reaction partners are clustered in areas with a diameter smaller than the diffusion length of the diffusing partner. The activated fraction of the fixed species determines the size of an active subregion of the cluster. Linear stabi...
متن کاملA Membrane-Bound Vertebrate Globin
The family of vertebrate globins includes hemoglobin, myoglobin, and other O(2)-binding proteins of yet unclear functions. Among these, globin X is restricted to fish and amphibians. Zebrafish (Danio rerio) globin X is expressed at low levels in neurons of the central nervous system and appears to be associated with the sensory system. The protein harbors a unique N-terminal extension with puta...
متن کاملMembrane-bound Ribosomes in Kidney
Membrane-bound ribosomes are thought to secrete protein for export and free ribosomes to secrete protein for intracellular use. The proportion of the total ribosomes that is bound to membranes in normal mouse kidneys has been estimated by three different methods, and the results have been compared with those obtained by a fourth method used by us previously. The most valid estimates appear to b...
متن کاملMembrane-bound ribosomes of myeloma cells. IV. mRNA complexity of free and membrane-bound polysomes
We have analyzed the sequence complexity, frequency distribution, and template activity of free (F) and membrane-bound (MB) polysomal mRNA populations of MOPC 21 (P3K) mouse myeloma cells. Using the technique of mRNA-cDNA hybridization, we find that F poly(A)+ RNA, which represent 60% of total polysomal mRNA, consists of approximately 8,000 different mRNA sequences distributed in three abundanc...
