WebNov 25, 2024 · The membrane arm of Ct-complex I contains one phosphopantetheine group as a cofactor bound to the second copy of subunit NDUFAB1 (NDUFAB1β) at the tip of the membrane arm. In addition to the cofactors, we identified 17 phospholipids and 14 detergent molecules in the cryoEM map of the DDM-solubilized complex I (Fig. 2, A and B). WebSep 13, 2012 · However, while aaRSs aminoacylate tRNA and supply building blocks for ribosomal translation, aa:CP ligases transfer activated amino acids to the phosphopantetheine group of small carrier proteins. We have solved the crystal structure of an aa:CP ligase complexed with the carrier protein (CP). how to sell on offerup online

WebAbstract. Acyl carrier protein represents one of the most highly conserved proteins across all domains of life and is nature's way of transporting hydrocarbon chains in vivo. Notably, type II acyl carrier proteins serve as a crucial interaction hub in primary cellular metabolism by communicating transiently between partner enzymes of the ... WebJun 1, 2011 · PKS acyl carrier protein (ACP) and NRPS petidyl carrier (PCP) domains within these modules require a post-translational activation by the attachment of a phosphopantetheinyl group to a conserved serine residue within the active site. This reaction is catalyzed by phosphopantetheinyl transferases (PPTases) that use coenzyme … WebMay 28, 2012 · Background: Modular polyketide synthases are multifunctional megasynthases which biosynthesize a variety of secondary metabolites using various combinations of dehydratase (DH), ketoreductase (KR) and enoyl-reductase (ER) domains. During the catalysis of various reductive steps these domains act on a substrate moiety … how to sell on olx south africa
