Lipoate–protein ligase

Lipoate–protein ligase (EC 2.7.7.63, LplA, lipoate protein ligase, lipoate–protein ligase A, LPL, LPL-B) is an enzyme with systematic name ATP:lipoate adenylyltransferase.[1][2][3][4][5][6][7] This enzyme catalyses the following chemical reaction

(1) ATP + lipoate diphosphate + lipoyl-AMP
(2) lipoyl-AMP + apoprotein protein N6-(lipoyl)lysine + AMP
