The cap homodimer (with bound camp) binds a 22-base-pair dna consensus sequence with a two-fold axis of symmetry. cap can be seen to induce a sharp bend of ~ 90o in target dna . each cap monomer has numerous contacts with its dna half site. the c-terminal domain of each cap monomer contains a helix-turn-helix (h-t-h) dna-binding motif found in most bacterial transcription factors. this motif is found, in a modified form (the homeodomain), in some eukaryotic transcription factors as well. the h-t-h motif confers dna-binding specificity. which of the following sets of amino acids are located on the recognition helix (green) of cap and bind to the bases lining the dna major groove? the cap homodimer (with bound camp) binds a 22-base-pair dna consensus sequence with a two-fold axis of symmetry. cap can be seen to induce a sharp bend of ~ 90o in target dna . each cap monomer has numerous contacts with its dna half site. the c-terminal domain of each cap monomer contains a helix-turn-helix (h-t-h) dna-binding motif found in most bacterial transcription factors. this motif is found, in a modified form (the homeodomain), in some eukaryotic transcription factors as well. the h-t-h motif confers dna-binding specificity. which of the following sets of amino acids are located on the recognition helix (green) of cap and bind to the bases lining the dna major groove? glu72, ser83, thr127 asn268, gly296, lys298, ser299 val139, lys26 arg180, glu181, arg185
