Protein crystals isolated from potato tubers were found to consist of a proteinase inhibitor active against the cysteine proteinases papain, chymopapain, and ficin. The molecular weight as determined by gel filtration at pH 4.3 or by gel electrophoresis in the presence of dodecylsulfate was 80 kilodaltons. When the inhibitor was evaluated at pH 8.4 in a(More)
A method for the solubilization and reconstitution of red beet (1,3)-beta-d-glucan synthase with the detergent 3-[(3-cholamidopropyl) dimethylammonio]-1-propane sulfonate (CHAPS) was developed. Glucan synthase was effectively solubilized from microsomal or plasma membranes by 0.6% CHAPS in the presence of EGTA and EDTA. Chelators were found essential for(More)
We present a study on connection errors in networks of linear features and methods of error detection. We model networks with special connection specifications as networks with hierarchically connected features and define errors considering the spatial relationships and the functionality of the network elements. A general definition of the problem of the(More)
The topic of this paper is the presentation of a new network model designed for networks consisting of spatial objects. This model allows the development of more advance representations of systems of networked objects and the study of geographical phenomena propagated through networks. The capabilities of the model in simulation of geographical phenomena(More)
