... encoding bridges a gap between two underspeci- fication formalisms, and speeds up the processing of Hole Semantics. 1 Introduction In the past few years there has been consider- able activity in the development ... hole h must denote the same node as a root P(h ). Further, every root that is not the root of the entire tree denotes the child of another root, i.e. deno...

... homology to the class I glutamine amidotransferase domain in GMP synthetase [45]. It has been postulated that, as glutamine synthetase and glutamine amidotransferase are involved in the addi- tion ... AtdA3, the largest substrate accepted by the WT AtdA, 2EA, was docked into the AtdA3 homology model. The approxi- mate initial position of the substrate was determined on the b...
