생명과학 中 효소 분류에 대한 서술 차이

게시글 주소: https://orbi.kr/00074821670

기존 2015 개정 교육과정에서는 생명과학2에서 효소를 아래의 6개로 분류했다.

그런데 2022 개정 교육과정 '세포와 물질대사' 과목에서는 하나가 추가돼 7개로 분류한다.

실제 생화학 책에서도 7개로 분류하고 있음을 볼 수 있다.


이는 IUBMB(국제 생화학・분자생물학 연합)이 효소 분류 체계인 EC number를 2018년에 개정하였기 때문에 자리옮김효소가 새로 추가된 것이다. 여기에는 ATP 합성효소, Na+/K+ 펌프가 포함된다. 






"Six enzyme classes have been recognized since the first Enzyme classification and nomenclature list was first approved by the International Union of Biochemistry in 1961. These were based on the type of reaction catalysed: Oxidoreductases (EC 1), Transferases (EC 2), Hydrolases (EC 3), Lyases (EC 4), Isomerases (EC 5) and Ligases (EC 6). However, it has become apparent that none of these could describe the important group of enzymes that catalyse the movement of ions or molecules across membranes or their separation within membranes. Several of these involve the hydrolysis of ATP and had been previously classified as ATPases (EC 3.6.3.-), although the hydrolytic reaction is not their primary function.

These enzymes have now been classified under a new EC class of translocases (EC 7).The reactions catalysed are designated as transfers from ‘side 1’ to ‘side 2’ because the designations ‘in’ and ‘out’ (or ‘cis’ and ‘trans’), which had been used previously, lack clarity and can be ambiguous. The comments associated with each entry then describe the specific translocations catalysed."





즉, 이제 효소 종류를 6개로 배운 사람들은 마치 요오드 망간 크롬 타이탄 세대처럼 틀딱이 된 거임
