Carrier proteins in polyketide synthase (PKS) and nonribosomal peptide synthase (NRPS) systems play an important role in syntheses of polyketides and nonribosomal peptides respectively (Figure 1). Carrier proteins are relatively small in size (80−100 amino acids; 8−10kDa) compared to other catalytic domains in a synthase system. The key role of carrier proteins is to serve as an attachment site...

A panel of chimeric carrier proteins was developed and screened for functional activity with essential enzymes involved in carrier protein-mediated biosynthesis. Regions on either side of the recognition helix II within three carrier proteins (CPs) from distinct biosynthetic pathways were swapped in all combinations to generate 24 mutated CPs. This panel of chimeric carrier proteins was tested ...

Evaluation of new acyl carrier protein hydrolase (AcpH, EC 3.1.4.14) homologs from proteobacteria and cyanobacteria reveals significant variation in substrate selectivity and kinetic parameters for phosphopantetheine hydrolysis from carrier proteins. Evaluation with carrier proteins from both primary and secondary metabolic pathways reveals an overall preference for acyl carrier protein (ACP) s...

acridine derivatives, especially 1,8-dioxo-9-aryl-decahydroacridine represent significant scaffolds in medicinal chemistry. given the biological properties of such products which are used in drug development, they need to have appropriate carrier. proteins are generally used as helpful tools in drug delivery. consequently, molecular docking between these compounds and bovine serum albumin (bsa)...
