Patent number: 9193962
Abstract: The invention provides hydrolases, polynucleotides encoding them, and methods of making and using these polynucleotides and polypeptides. In one aspect, the invention is directed to polypeptides, e.g., enzymes, having a hydrolase activity, e.g., an esterase, acylase, lipase, phospholipase (e.g., phospholipase A, B, C and D activity, patatin activity, lipid acyl hydrolase (LAH) activity) or protease activity, including thermostable and thermotolerant hydrolase activity, and polynucleotides encoding these enzymes, and making and using these polynucleotides and polypeptides. The hydrolase activities of the polypeptides and peptides of the invention include esterase activity, lipase activity (hydrolysis of lipids), acidolysis reactions (to replace an esterified fatty acid with a free fatty acid), transesterification reactions (exchange of fatty acids between triglycerides), ester synthesis, ester interchange reactions, phospholipase activity and protease activity (hydrolysis of peptide bonds).

Abstract: Compositions, methods, strategies, kits, and systems for the delivery of negatively charged proteins, protein complexes, and fusion proteins, using cationic polymers or lipids are provided. Delivery of proteins into cells can be effected in vivo, ex vivo, or in vitro. Proteins that can be delivered using the compositions, methods, strategies, kits, and systems provided herein include, without limitation, enzymes, transcription factors, genome editing proteins, Cas9 proteins, TALEs, TALENs, nucleases, binding proteins (e.g., ligands, receptors, antibodies, antibody fragments; nucleic acid binding proteins, etc.), structural proteins, and therapeutic proteins (e.g., tumor suppressor proteins, therapeutic enzymes, growth factors, growth factor receptors, transcription factors, proteases, etc.), as well as variants and fusions of such proteins.
