    摘要: There are described certain subtilisins wherein the amino acid sequence of such subtilisins has been modified at a position equivalent to +225 in Bacillus amyloliquefaciens, such that an amino acid selected from the group consisting of alanine, leucine, methionine, glutamine, valine, and serine, has been substituted for the amino acid residue naturally occurring at such position.

    摘要: The present invention provides a solid material comprising an immobilized mixture of two or more proteorhodopsins, two or more bacteriorhodopsins, or one or more bacteriorhodopsin and one or more proteorhodopsins. The proteorhodopsins are selected from the group consisting of all-trans-retinal-containing proteorhodopsins and retinal analog-containing proteorhodopsins; all of which have absorption spectra that do not overlap. The bacteriorhodopsins are selected from the group consisting of all-trans-retinal-containing bacteriorhodopsins and retinal analog-containing bacteriorhodopsins; all of which have absorption spectra that do not overlap. The present invention also provides an optical information carrier, such as an optical data storage material and a fraud-proof optical data carrier, comprising the above-described solid material and a substrate selected from the group consisting of glass, paper, metal, fabric material, and plastic material, wherein said solid material is deposited on said substrate. The present invention further provides security ink comprising one or more hydrophilic polymers and a mixture of various photochromic materials.

    摘要: The present invention relates to a method for preparing a variant lipolytic enzyme comprising expressing in a host organism a nucleotide sequence which has at least 90% identity with a nucleotide sequence encoding a fungal lipolytic enzyme and comprises at least one modification at a position which corresponds in the encoded amino acid sequence to a) the introduction of at least one glycosylation site in the amino acid sequence compared with the original fungal lipolytic enzyme; b) the introduction of at least one amino acid at a surface position and at a location in an external loop distal to the active site of the enzyme which is more hydrophilic; or c) a substitution or insertion at one or more of positions disclosed herein or a deletion at one or more positions disclosed herein. The invention also relates to polypeptide produced by the method and to novel nucleic acids.
