Description
본 발명은 내염성 감마-글루타밀 트랜스펩티데이즈를 생산하는 신규한 호염성 바실러스 폴리퍼멘티쿠스(Bacillus polyfermenticus) 균주(KCTC11751BP) 및 이를 이용한 감마-글루타밀 트랜스펩티데이즈 생산 방법에 관한 것이다.The present invention relates to a novel Bacillus polyfermenticus strain (KCTC11751BP) for producing flame-resistant gamma-glutamyl transpeptides and a method for producing gamma-glutamyl transpeptides using the same.
감마-글루타밀 트랜스펩티데이즈(gamma-glutamyl transpeptidase)는 글루타치온(Glutathione)과 같은 물질에서 글루타밀 결합을 끊어, 글루타밀 일부분을 물에 전달하는 가수분해 작용과 다른 아미노산 또는 펩타이드에 전달하는 트랜스펩티데이션(transpeptidation) 작용을 하는 효소이다. 이 효소는 글루타치온 대사과정에 관여하며, 항산화 방어, 해독작용, 염증반응에서 중요한 역할을 한다. 또한, 이 효소는 음식 산업에 활용이 가능하다. 예를 들어, 아미노산의 쓴맛 개선, 발효 음식의 감칠맛 증진 등의 효과가 증명되어 식품 산업에서 다양하게 활용이 가능하다.Gamma-glutamyl transpeptidase breaks glutamyl bonds in substances such as glutathione, and it is a hydrolytic activity that transfers a portion of glutamyl to water and a transpeptide that transfers it to other amino acids or peptides. It is an enzyme that acts as a transpeptidation. This enzyme is involved in glutathione metabolism and plays an important role in antioxidant defense, detoxification and inflammatory reactions. The enzyme can also be used in the food industry. For example, the effects of improving the bitter taste of amino acids and enhancing the umami of fermented foods have been proved, and thus can be variously used in the food industry.
감마-글루타밀 트랜스펩티데이즈를 생산하는 효소 생산균주로서 호염성의 균주 또한 활용 가능성이 높다. 발효 식품인 김치의 초기 발효에는 바실러스 균주가 중요한 역할을 한다. 그 이유는 바실러스 균주가 생산하는 효소는 김치와 젓갈 속의 단백질을 분해하여 유용한 펩타이드를 생산하며, 김치의 풍미를 증진시키는 역할을 하기 때문이다. 김치는 소금, 젓갈을 이용하여 발효시키기 때문에 염 농도가 일반 식품에 비해 높은 편이다. 따라서 호염성의 바실러스 균주는 염 농도가 높은 발효 환경에서 작용 범위가 넓다. 지금까지 탐색 개발된 것은 고활성의 효소로서, 호염성 바실러스 균은 개발된 예가 많지 않다. 그러므로, 호염성의 효소를 생산하는 호염성의 바실러스 균주는 식품 분야에서 활용 가치가 넓을 것으로 사료된다.Basophilic strains as enzyme producing strains producing gamma-glutamyl transpeptides are also highly applicable. Bacillus strains play an important role in the initial fermentation of kimchi, a fermented food. The reason is that the enzyme produced by the Bacillus strain breaks down proteins in kimchi and salted fish to produce useful peptides, and serves to enhance the flavor of kimchi. Kimchi is fermented with salt and salted fish, so the salt concentration is higher than that of general foods. Thus, basophil Bacillus strains have a wide range of action in a fermentation environment with high salt concentration. So far, it has been developed and explored as a highly active enzyme, and there are not many cases of basophilic Bacillus bacteria. Therefore, basophilic strains producing basophilic enzymes are considered to be of great value in the food field.
