We sketch and illustrate an approach to machine translation that exploits the potential of simultaneous correspondences between separate levels of linguistic representation, as formalized in the LFG notion of codescriptions. The approach is illustrated with examples from English, German and French where the source and the target language sentence show(More)
We have discovered a superfamily of enzymes related by their ability to catalyze the abstraction of the alpha-proton of a carboxylic acid to form an enolic intermediate. Although each reaction catalyzed by these enzymes is initiated by this common step, their overall reactions (including racemization, beta-elimination of water, beta-elimination of ammonia,(More)
This paper describes two algorithms which construct two different types of generators for lexical functional grammars (LFGs). The first type generates sentences from functional structures and the second from semantic structures. The latter works on the basis of extended LFGs, which contain a mapping from f-structures into semantic structures. Both(More)
The equilibrium mixture of yeast enolase with substrate, 2-phospho-D-glycerate (2-PGA), and product, phosphoenolpyruvate (P-enolpyruvate), has been crystallized from solutions of poly(ethylene glycol) (PEG) at pH 8.0. Crystals belong to the space group C2 and have unit cell dimensions a = 121.9 A, b = 73.2 A, c = 93.9 A, and beta = 93.3 degrees. The(More)
The structure of a new crystal form of enolase from bakers' yeast has been solved to 2.1-A resolution. Crystals were grown from poly(ethylene glycol) and KCl at pH 8.2 in the presence of Mg2+ and a reaction intermediate analog, phosphonoacetohydroxamate (PhAH). Crystals belong to space group C2; have unit cell dimensions a = 123.5 A, b = 73.9 A, and c =(More)
Galactose-1-P uridylyltransferase purified from Escherichia coli cells grown in enriched medium contains approximately 1.2 mol of tightly bound zinc/mol of subunits as well as variable amounts of iron, up to 0.7 mol/mol of subunits, and no detectable Ca, Cd, Cu, Mo, Ni, Co, Mn, As, Pb, or Se. The chelators, 1,10-phenanthroline, 8-hydroxyquinoline,(More)
