ELSEVIER Enzymes Glucose Isomerases With an Altered pH Optimum Lambeir et al Gist-Brocades NV (De&. Netherlands); Plant Genetic Systems NV (Brussels, Belgium) US 5384257; January 24, 1995 A method for selecting amino acid residues which, upon replace- ment, will give rise to an enzyme with an altered pH optimum. The method is specific for metalloenzymes that are inactivated at low pH as a result of the dissociation of the metal ions. Pectin-Modified Lipase From Mucorjuvanicus With Lowered Saturated/Unsaturated Fatty Acid Ratio Chmiel et al Nestec SA (Vevey, Switzerland) US 5384256; January 24, 1995 A native lipase from Mucor javanicus modified by bonding it to a pectin. The pectin-modified lipase releases fatty acids of identical chain length from a lipidic substrate in a lower saturated-to- unsaturated fatty acid ratio than the native, unmodified lipase. Method of Effecting Increased Performance of Diagnostic Enzyme Reaction Systems Using Noble Gases Spencer American Air Liquide (Walnut Creek, CA) US 5382525; January 17, 1995 A method of effecting increased performance of diagnostic en- zyme reaction systems that includes contacting at least one reagent of an enzyme-diagnostic kit during use of the reagent in conjunc- tion with the kit with a noble gas.

Process for the Preparation of L-Serine by an Enzymatic Method Fukuhara et al Mitsui Toatsu Chemicals, Inc. (Tokyo, Japan) US 5382517; January 17, 1995 A process for preparing L-serine from glycine and formaldehyde in the presence of cells of a microorganism or a cell-treated product having a serine hydroxymethyl transferase activity by an enzymat- ic method.

(Indianapolis, IN) US 5382527; January 17, 1995 A method for isolating transposable elements used to isolate an approximately 1.6-kb insertion sequence from Streptomyces. The method entails transforming a cell with a plasmid containing a repressor gene, so that the introduction of a transposable element into the gene allows the expression of a selectable marker in a second host cell.
