The present invention relates to compositions (i.e., various organic small molecules as exemplified herein) and methods for the inhibition of protein splicing and especially relates to the inhibition of protein autosplicing of intein-containing proteins. Additionally, the present invention relates to the use of the inhibitors of protein splicing of the invention for the treatment of various diseases including but not limited to tuberculosis. Furthermore, the invention provides the first instance of small molecule inhibitors of protein splicing with drug-like characteristics.

Methods and compositions for specific inhibition of protein splicing by small molecules

A new type of transgene system is disclosed which allows efficient protein expression in a target host such as a plant, but avoids the undesirable result of the migration of the transgene into related host system and/or to the environment via the pollen. The methods described herein may also be applied to the expression of virtually any protein of interest (e.g. a toxic protein) in eukaryotic (yeast, insect, mammalian cells, etc.) and prokaryotic (, etc.) organisms.

Method for generating split, non-transferable genes that are able to express an active protein product

Disclosed are methods for the production of second generation catalytic antibodies. The disclosed methods offer a variety of advantages relative to prior art techniques. For example, the methods of the present invention do not require prior identification of the active site of an enzyme, the activity of which is desired in the catalytic antibody. Additionally, the disclosed methods enable the production of antibodies which catalyze chemical reactions which do not occur in nature.

Anti-idiotype vaccines to elicit catalytic antibodies

A homogenous sample of identical bispecific antibody determinants, each determinant being composed of two L-H half-molecules linked by disulfide bonds, each L-H half-molecule being specific for a different antigenic determinant and including at least the F(ab') portion of a monoclonal IgG antibody. The bispecific antibody determinants are useful, e.g., in the formation of multilamellar assemblies and in enzymatic assays.
