  Described are monomer compositions containing aspartic acid and other comonomers, such as monosodium aspartate, and methods for their production. The monomer compositions can be polymerized, particularly by thermal polymerization, to obtain useful and novel imide-containing polyamino acids, i.e., copolymers containing polymerized aspartate units and succinimide units. The invention is also directed to the resulting polymeric materials, their methods of production, and their uses. Uses of the imide-containing polyamino acids include, for example, dispersants in detergents and cleansers, water-treatment chemicals as anti-scalants and corrosion inhibitors, personal-care additives for softening and moisturizing, and many others.

  Immobilized enzymes, intermediates therefor, and a process for the preparation of such substances are described. The method comprises reacting an enzyme with a polymerizable, ethylenically, unsaturated monomer containing a reactive group, and then polymerizing or copolymerizing the covalently-bonded enzyme-monomer product thus produced in the presence of a cross-linking agent and an initiator. The process affords immobilized enzymes of high stability and activity.

  Truncated derivatives of aspartase having enhanced catalytic activity and/or enhanced clot dissolution properties relative to native aspartase from E. coli. The enzymes are isolated by site-directed mutagenesis of DNA encoding aspartase. L-aspartic acid is manufactured by contacting fumarate and ammonium ion in the presence of an aspartase derivative.
