Disease

[ACAD8_HUMAN] Defects in ACAD8 are the cause of isobutyryl-CoA dehydrogenase deficiency (IBDD) [MIM:611283]. The symptoms of IBDD generally appear until late in infancy or in childhood and can include poor feeding and growth (failure to thrive), a weakened and enlarged heart (dilated cardiomyopathy), seizures, and low numbers of red blood cells (anemia).[1][2][3]

Function

[ACAD8_HUMAN] Has very high activity toward isobutyryl-CoA. Is an isobutyryl-CoA dehydrogenase that functions in valine catabolism. Plays a role in transcriptional coactivation within the ARC complex.[4][5]

About this Structure

1rx0 is a 4 chain structure with sequence from Homo sapiens. Full crystallographic information is available from OCA.
