초록

토양으로부터 분리한 P. polymyxa 균주가 생산하는 CFTase의 각 repeat region의 결손 변이체를 제작하였으며 그에 따른 야생형 효소와 변이 효소의 활성변화 및 효소특성을 비교 검토하였다. 야생형 CFTase를 CFT148로, N-말단의 R1과 R3를 제거한 결손변이체 CFTase를 CFT108로, C-말단의 R4를 제거한 결손변이체는 CFT130, 모든 R 영역을 제거한 것은 CFT88로 명명하였다. 각각 정제된 재조합 단백질은 148 kDa, 108 kDa, 130 kDa, 그리고 88 kDa의 크기를 나타내었다. Inulin을 기질로 각 재조합 단백질의 활성을 검토한 결과 CFT108은 CF생성, CF분해 반응을 모두 가지고 있었으며 CFT130, CFT88의 경우에는 CF생성 활성을 나타내지 않았으며 endo-inulinae와 동일한 inulin 분해활성을 나타내었다. 따라서 N-말단의 repeat region인 R1과, R3의 역할은 균체 외로의 분비를 담당하며 C-말단의 R4영역은 CFTase의 중요 활성인 cyclization반응을 담당하고 있는 것으로 확인되었다. Repeat region의 모두 제거한 결손 변이체는 기질 inulin을 F2-F4 사이의 중합도를 가진fructooligosaccharide를 생산하는 endo-inulinase의 활성을 가지고 있었다. CFTase는 다기능 효소로 여러 domain으로 구성되어 있으며 각 domain의 결손에도 단백질의 활성을 유지하였으며, 특히 결손 변이체 CFT108은 고효율의 CF 생산이 가능하여 산업적으로 유용하게 사용될 수 있는 효소이다.

Cycloinulooligosaccharide fructanotransferase (CFTase) converts inulin into cycloinulooligosaccharides (cyclofructan, CF) of ${\beta}-(2{\to}1)$-linked D-fructofuranose as well as hydrolysis of cyclofructan. Sequences analysis indicated that CFTase was divided into five distinct regions containing three repeated sequences (R1, R3, and R4) at the N-terminus and C-terminus. Each domain function was investigated by comparison of wild type CFTase enzyme (CFT148) and deletion mutant proteins (CFT108: R1 and R3 deletion; CFT130: R4 deletion; and CFT88: R1, R3, and R4 deletion) of CFTase. The CFT108 mutant had both CFTase and CF hydrolyzing activity as CFT148 did. CFTase activities and CF hydrolysing activities were disappeared in CFT130 and CFT88 mutants. These results indicated that the C-terminal R4 region of P. polymyxa CFTase is necessary for cyclization and hydrolyzing activity.
