Methods and compositions for rendering nucleic acids directly responsive to an external signal utilizing modulators that themselves respond to the external signal and are associated with the nucleic acid. In response to the external signal, the modulator alters physical properties of the specific nucleic acid molecule(s) with which it is associated, thereby altering the structural and functional properties thereof. The modulator may, for example, transfer applied energy to a nucleic acid, or to a portion of the nucleic acid, thereby changing the nucleic acid structure.

Disclosed are novel isolated nucleic acids and substantially pure protein preparations for naturally occurring and synthetic or chimeric heparan sulfate D-glicosaminyl 3-O-sulfo-transferases (3-OSTs). Also disclosed are uses for these genes and proteins, including uses for the modification and sequencing of glycosaminoglycans.

Heparan sulfate D-glucosaminyl 3-O-sulfotransferases, and uses therefor

A versatile modular peptide mediated intracellular delivery system is disclosed which may be particularly adapted to facilitate the delivery of therapeutic compounds which are large in size or complex in nature. The invention relates both to a modular peptide mediated intracellular delivery system and a method of delivering a compound into a cell using the system.
