2.3.1.199 | additional information | the 3-ketoacyl-CoA reductase, KAR, the enzyme catalyzing the next step in metabolism after fatty acid elongase ELOVL6, largely stimulates ELOVL6 activity. Activity of purified enzyme ELOVL6 is enhanced by about 3fold in the presence of 3-ketoacyl-CoA reductase, KAR. This effect is KAR enzyme activity-independent, since it is observed in the absence of NADPH and in the poorly active or inactive KAR mutants, overview. ELOVL6 enzyme activity is also enhanced in a KAR enzyme activity-dependent manner | Homo sapiens | |
2.3.1.199 | NADPH | ELOVL6 activity in membrane fractions is enhanced in the presence of NADPH | Homo sapiens |

2.3.1.199 | physiological function | 3-ketoacyl-CoA reductase, KAR, regulates enzyme ELOVL6 via two modes: in the first mode, KAR may induce conformational changes in ELOVL6 to become a structure that can undergo catalysis. In the second mode, conversion of 3-oxoacyl-CoA to 3-hydroxyacyl-CoA by KAR may facilitate release of the product from the presumed ELOVL6-KAR complex | Homo sapiens |
