摘要:
Provided is a mutant of propionyl-CoA transferase from Clostridium propionicum that can convert lactate into lactyl-CoA with high efficiency in a method of preparing a polylactate (PLA) or PLA copolymer using microorganisms. Unlike conventional propionyl-CoA transferase which is weakly expressed in E. coli, when a mutant of propiony-CoA transferase from Clostridium propionicum is introduced into recombinant E. coli, lactyl-CoA can be supplied very smoothly, thereby enabling highly efficient preparation of polylactate (PLA) and PLA copolymer.

摘要:
Provided is a method of preparing polylactate (PLA) or a copolymer thereof using a mutant microorganism in which a gene participating in a coenzyme A (CoA) donor- and lactate-producing pathway is genetically manipulated to increase the productivity of a CoA donor and lactate. Amounts of the CoA donor and the lactate are simultaneously increased in a microbial metabolic pathway to enable effective biosynthesis of PLA and a hydroxyalkanoate-lactate copolymer having a high content of lactate, which is industrially useful.

摘要:
Mutants of various polyhydroxyalkanoate (PHA) synthases capable of synthesizing a lactate polymer (PLA) and a lactate copolymer (PLA copolymer), and a method of preparing a lactate polymer and a lactate copolymer using the same are provided. More specifically, a mutant of polyhydroxyalkanoate synthase set forth in SEQ ID NO: 2, 4, 6, or 8, and a method of preparing lactate polymer and lactate copolymer using the mutant of synthase are provided. The polyhydroxyalkanoate synthase set forth in SEQ ID NO: 2, 4, 6, or 8 can have an activity of synthesizing a lactate polymer and a lactate copolymer by an amino acid sequence mutation affecting an activity of synthesizing a lactate polymer, and can produce a lactate polymer and a copolymer that have different features, respectively, by using the mutants of the synthase.

摘要:
Provided are a use of a lipolytic enzyme for forming anti-fingerprint coating, a method of forming anti-fingerprint coating including treating a substrate with a composition comprising the lipolytic enzyme, a substrate including the anti-fingerprint coating formed by the same method, and a product including the same. The anti-fingerprint coating can reduce contamination of display devices, appearances of electronic devices or building materials by fingerprints.
摘要:
Provided are a porous structure for forming anti-fingerprint coating capable of providing a self-cleaning function to a surface of a substrate, a method of forming anti-fingerprint coating using the same, an anti-fingerprint coated substrate prepared by the same method, and a product including the same. When the porous structure including a lipolytic enzyme is formed on the surface of the substrate, contaminants decomposed by an enzyme are absorbed into a pore, and thus anti-fingerprint coating may be more effectively performed to remove detectable contamination from a surface of the substrate. As a result, contamination by fingerprints on the surface of a display device, the appearance of an electronic device, or building materials can be effectively reduced.
