WebBiotinylation of oligonucleotides. Immobilize the biotin-labeled DNA/RNA target sequence onto the beads and incubate with the cell extract. You can then isolate the bound proteins using magnetic separation. You can elute off the protein for characterization or apply the whole solid-phase complex directly, e.g., to DNase footprinting studies. WebBiotin ligase BirA controls biotin synthesis in Escherichia coli. It sends biotin to metabolism. As a homodimer, it negatively controls the biotin synthetic operon. BirA also catalyzes post-translational biotinylation, by associating with biotin acceptor protein of acetyl-coenzyme A carboxylase. [ 1] [ 2] It can biotinylate human histones. [ 3]
WebNov 2, 2024 · The process of fatty acid synthesis starts with the carboxylation of acetyl-CoA to form malonyl-CoA (figures 4.16 and 4.17). The enzyme involved, acetyl-CoA carboxylase, is the regulatory enzyme for this pathway and requires biotin as a cofactor. Web2 days ago · Here, we describe the design and synthesis of a MX-biotin probe (MXP) and negative control (MXP-NC) that can be used to define MX's cellular targets and expand our understanding of the proteome-wide profile for MX.
