REFINEMENT PROTOCOL--RIGID BODY FIT OF TRNA DETAILS--the tRNA coordinate files
were fitted to the E. coli translation initiation complex map (EMBL-EMD 3525)
in the following way- first the cross-correlation of the respective 30S subunit
maps were maximized and the resulting transformation matrix was computed.
second the coordinates of the tRNA models were transformed according to the
matrix previously computed.
