WebOct 8, 2012 · The ACP serine residue that anchors the phosphopantetheine arm, S35, is positioned at the amino terminus of the ACP-α2 helix. Ionic Contacts Rigidly Position ACP-α2 Relative to BioH. The contacts between BioH and the ACP molecule are mediated solely by the ACP-α2 helix and the second and third α helices of the BioH capping domain ( Fig. S4 ). WebOct 29, 2024 · Pantothenate kinase-associated neurodegeneration (PKAN) is an autosomal recessive movement disorder affecting children and adults. This profoundly disabling disorder manifests with severe, painful dystonia, young-onset parkinsonism, globus pallidus iron accumulation, and blindness from pigmentary retinopathy (Hayflick et al, 2003 ).
