DNA RECOGNITION BY GAL4: STRUCTURE OF A PROTEIN/DNA COMPLEX

DNA recognition by GAL4: structure of a protein-DNA complex.

DNA (5'-D(*CP*CP*GP*GP*AP*GP*GP*AP*CP*AP*GP*TP*CP*CP*TP*CP*C P*GP*G)-3')

DNA (5'-D(*CP*CP*GP*GP*AP*GP*GP*AP*CP*TP*GP*TP*CP*CP*TP*CP*C P*GP*G)-3')

RESIDUES LEU A 19 - LYS A 27 AND LEU B 19 - LYS B 27 FORM TIGHT TURNS WHICH CONNECT HELICES. RESIDUES TRP A 39 - LEU A 49 AND TRP B 39 - LEU B 49 FORM EXTENDED CHAINS WHICH CONNECT HELICES.

THE TRANSFORMATION PRESENTED ON *MTRIX* RECORDS BELOW WILL YIELD APPROXIMATE COORDINATES FOR CHAIN *B* WHEN APPLIED TO CHAIN *A*.

PROTEIN-DNA COMPLEX, DOUBLE HELIX, TRANSCRIPTION-DNA COMPLEX
