Abstract:
The present invention relates to lipase having a novel 1,3-amino acid sequence or 5-amino acid sequence from Bacillus pumilus separated from microorganisms living in antarctic and, more specifically, to a novel lipase having high activity at a low temperature and under a high alkali state, to provide the lipase and a gene for coding the lipase.
Abstract:
PURPOSE: Ramalin using a glutamic acid derivative and hydroxyaniline or hydroxyaniline with a protected hydroxy group and a synthesis method of a ramalin precursor are provided to synthesize ramalin with excellent antioxidant effect and anti-inflammation effect through a simple process without using DMF having potent toxicity. CONSTITUTION: A synthesis method of ramalin comprises the steps of: reacting a glutamic acid derivative indicated as the following chemical formula 2 and a hydrazine salt compound indicated as the following chemical formula 3 and hydrogenating the compound indicated as the following chemical formula 4 generated by the reaction above to produce ramalin indicated as the following chemical formula 1. The glutamic acid derivative indicated as the following chemical formula 2 is produced by reacting a glutamic acid derivative indicated as the following chemical formula 5 and alkylchloroformate having a structure of R^1-O-CO-Cl.
