    摘要： Novel carbonyl hydrolase mutants derived from the DNA sequences of naturally-occurring or recombinant non-human carbonyl hydrolases are disclosed. The mutant carbonyl hydrolases, in general, are obtained by in vitro modification of a precursor DNA sequence encoding the naturally-occurring or recombinant carbonyl hydrolase to generate the substitution of one or more amino acid residues in the amino acid sequence of a precursor carbonyl hydrolase. Such mutant carbonyl hydrolases have properties which are different from those of the precursor hydrolase and are especially useful in detergent formulations. The substituted amino acid residues correspond to position +123 and/or +274 in Bacillus amyloliquefaciens subtilisin.

    摘要： Novel carbonyl hydrolase variants derived from the DNA sequences of naturally-occurring or recombinant non-human carbonyl hydrolases are disclosed. The variant carbonyl hydrolases, in general, are obtained by in vitro modification of a precursor DNA sequence encoding the naturally-occurring or recombinant carbonyl hydrolase to generate the substitution of a plurality of amino acid residues in the amino acid sequence of a precursor carbonyl hydrolase. Such variant carbonyl hydrolases have properties which are different from those of the precursor hydrolase, such as altered proteolytic activity, altered stability, etc. The substituted amino acid residues correspond to positions +76 in combination with one or more of the following residues +99, +101, +103, +104, +107, +123, +27, +105, +109, +126, +128, +135, +156, +166, +195, +197, +204, +206, +210, +216, +217, +218, +222, +260, +265 and/or +274 in Bacillus amyloliquefaciens subtilisin.

    摘要： Textile fibers are treated with enzymes in the absence of surfactants, with the effect of increasing the wettability and absorbency of the fibers. The enzymes are pectinases, cellulases, proteases, lipases or combinations thereof. The wetting properties of cotton fibers are found to be most substantially improved by treatment with a mixture of cellulase and pectinase. The effects of five hydrolyzing enzymes on improving the hydrophilicity of several polyester fabrics have been studied. Four out of the five lipases studied improve the water wetting and absorbent properties of the regular polyester fabrics more than alkaline hydrolysis under optimal conditions (3N NaOH at 55.degree. C. for 2 hours). Compared to aqueous hydrolysis, the enzyme reactions have shown to be effective under more moderate conditions, including a relatively low concentration (0.01 g/L), a shorter reaction time (10 minutes), at an ambient temperature (25.degree. C.). Contrary to the results with alkaline hydrolysis, the improved water wettability is accompanied by full strength retention. Lipase has also shown to be effective in improving the wetting and absorbent properties of sulfonated polyester and microdenier polyester fabrics.
