    摘要: The present invention relates to optionally substituted, non-toxic peptides and derivatives capable of inhibiting superoxide production in phagocytic cells. The invention also relates to compositions and methods useful in inhibiting inflammation and in treating inflammatory disorders such as autoimmune disorders, gout, adult respiratory distress syndrome, asthma, myocardial infarction, and various dermatological disorders. The present invention contemplates compositions derived from low molecular weight GTP-binding proteins (LMWG), mastoparan, GAP proteins, and related peptides. The invention further contemplates compositions useful in inhibiting activation of NADPH oxidase or in promoting GDP/GTP exchange. Therapeutic compositions containing various inhibitors, and methods of using same, are also disclosed.

    摘要: The present invention provides a GTP binding protein containing the following amino acid sequence, with a molecular weight of about 22K dalton and having GTP binding activity which is inhibited by N-ethyl-maleimide and GTP hydrolyzing activity:Thr-Ile-Glu-Asp-Ser-Tyr, and a method for the production of a GTP binding protein, which comprises introducing a DNA fragment containing DNA that encodes the GTP binding protein into a cloning site present at the downstream to a promoter of an expression vector, then introducing the expression vector thus constructed into a host, culturing said host, thereby expressing and accumulating the GTP binding protein and then collecting thereof.
