Nitrosylation is the general term for covalent incorporation of a nitric oxide "nitrosyl" moiety into another (usually organic) molecule. There are multiple chemical mechanisms by which this can be achieved; including biological enzymes and industrial processes. The biological functions of nitrosylation are particularly important as S-nitrosylation, the conjugation of NO to cysteine thiols in proteins, is an important part of cell signalling. Coordination of NO to transition metals to give metal nitrosyl complexes, is also referred to as nitrosylation.

The new method for treating the nitrogen oxide waste gas comprises three key links, namely efficient absorption of an organic solvent, catalytic oxidation and subsequent water extraction, wherein the organic solvent is a mixed organic solvent mainly comprising one or more esters, alcohols and ketones; nitrogen monoxide and oxygen which are absorbed by the organic solvent are oxidized into nitrogen dioxide and dinitrogen trioxide under the catalytic action of a rare earth complex, and then water extraction is carried out, so as to obtain an aqueous solution of dinitrogen trioxide, nitrous acid and nitric acid; the aqueous solution can be applied to a nitration and nitrosylation reaction or be recycled as an oxidizing agent, and the organic solvent can be recycled and applied to absorption of nitrogen monoxide; the rare earth complex has the catalytic oxidation function and is formed by rare earth and a phenolic ester compound, and complexing capacity of the rare earth complex is approximate to that of rare earth and nitrogen oxide. The new method for treating the nitrogen oxide waste gas is applicable to absorption, conversion and utilization of low-concentration nitrogen oxide, and harm to the environment owning to emission of waste gas is eliminated.

Detection of nitrosylated proteins
The present invention, in some aspects, relates to systems and methods for determining oxidized proteins, including nitrosylated proteins such as S-nitrosylated proteins. The systems and methods of the invention can be used in vitro (e.g., in cell or tissue culture) or in vivo. For instance, in some cases, the invention can be used to spatially determine the location and / or concentration of oxidized proteins within cells and / or tissues (e.g., through visual detection). In one set of embodiments, a nitrosylated or otherwise oxidized moiety on a protein may be reacted with a detection entity, which may be, for example, fluorescent, radioactive, electron-dense, able to bind to a signaling entity or a binding partner in order to produce a signal, etc. As a specific example, a nitrosothiol moiety on a nitrosylated protein may be reacted with an alkylating agent to form an alkylthio moiety; the alkylthio moiety may include a detection entity or otherwise be able to interact with a signaling entity. In some embodiments, other moieties on the protein may be altered or blocked before reaction of the protein with the detection entity. Such moieties on the protein may be, for instance, non-oxidized or non-nitrosylated moieties able to react with the detection entity. As a particular example, in a protein containing nitrosothiol and (non-nitrosylated) thiol moieties, the thiol moieties may first be altered or blocked prior to reaction of the protein with the detection entity. Also provided in certain aspects of the present invention are kits for determining oxidized proteins, which may include components such as detection entities, alkylating agents, blocking agents, reducing agents, signaling entities, binding partners, antibodies, instructions, and the like.

The invention discloses a small peptide TAT-AVPY for treating ischemic brain damage, and an application thereof. The complete sequence of the small peptide TAT-AVPY is H-YGRKKRRQRRR-AVPY-OH, represented by SEQ ID NO:1. With the small peptide TAT-AVPY provided by the invention, the binding of XIAP and proaspase-9 (Casp 9) can be reduced; nitrosylation of XIAP and proaspase-9 (Casp 9) can be alleviated; and proaspase-9 activation can be alleviated. Therefore, cell apoptosis induced by cerebral ischemia can be alleviated. Also, TAT can directly bring fused small peptide into cells, such that a problem of the approach for the drug to enter cells is solved, and medication is convenient. The small peptide TAT-AVPY has no immunogenicity, and does not cause an immune response of a body. Therefore, side effects are reduced, and the effectiveness of secondary medication or more is ensured.
