연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract AI-Helper 아이콘AI-Helper

Proteus vulgaris K80 lipase was expressed in Escherichia coli BL21 (DE3) cells and immobilized on amine-terminated magnetic microparticles (Mag-MPs). The immobilization yield and activity retention were 84.15% and 7.87%, respectively. A homology model of lipase K80 was constructed using P. mirabilis...

제안 방법

  • One of the most interesting ways to use immobilized enzymes is through their ability to be recovered and used multiple times [14]. In this study, the recovery ability of immobilized K80 was evaluated by repeating the pNPC assay 10 times. The immobilized K80 activity decreased gradually but retained >80% of initial activity after five reactions and about 42% after 10 reactions (Fig.

대상 데이터

  • p-Nitrophenyl esters, tributyrin, tricaprylin, fish oil, coconut oil, olive oil, and soybean oil were purchased from Sigma-Aldrich (St. Louis, MO, USA). Castor oil was acquired from the OCI Co.

이론/모형

  • The homology model of lipase K80 (Fig. 3A) was constructed through the SWISS-MODEL homology modeling server using the P. mirabilis structure as the template. P.
  • 1) was submitted to the SWISS-MODEL homology modeling server [1, 2], and modeling was performed in the automatic mode. The homology model was based on the crystal structure (PDB code: 4GW3) of P. mirabilis lipase with 80% amino acid identity [9].
  • aHydrolytic activity of soluble lipase K80 in the supernatant was measured using pNPC method.
  • bHydrolytic activity of immobilized lipase K80 on beads was measured using pNPC method.
