Model for the peroxisomal cofactor transport in plants. CTS: peroxisomal ABC transporter, mediating the import of fatty acids as acyl-CoA esters; FA: fatty acid; LACS6/7: long-chain acyl-CoA synthetase 6 and 7 (associated at the matrix site of the peroxisomal membrane); NMN(H): nicotinamide mononucleotide (reduced); PAP: adenosine 3′,5′-diphosphate; 4′-PP: 4′-phospho-pantetheine; PNC, peroxisomal ATP carrier; PXN, peroxisomal NAD carrier; (?): proposed cofactor carrier proteins.
