5' Hammerhead MammoBlock

This sequence, along with BBa_K779315, is designed to test the functionality of a hammerhead ribozyme in vitro. Hammerhead ribozymes are self-cutting strands of catalytic RNA. After a hammerhead ribozyme is transcribed in a cell, it folds into a secondary structure, which causes self-cleavage. Because of their RNA-cleaving function, hammerheads may be used to regulate protein expression and to make other RNA parts. For more information on hammerheads in general, see http://en.wikipedia.org/wiki/Hammerhead_ribozyme .

This sequence is designed for in vitro transcription - a promoter and terminator corresponding to the in vitro transcription kit should be attached via PCR. After IVT, the RNA transcript should be analyzed on a gel, to determine whether cleavage occurred.

This sequence is called a 5' hammerhead because its cut site is near its 5' end. The corresponding loss-of-site mutation, which should not cleave, serves as a control.
