THE ATOMIC STRUCTURE REMARK 3 OF ERA WAS FITTED AS 3 RIGID REMARK 3 BODIES, N-TERMINAL DOMAIN, C- REMARK 3 TERMINAL DOMAIN AND C-TERMINAL REMARK 3 HELIX WITHIN THE C-TERMINAL REMARK 3 DOMAIN. THE RESULTANT ERA REMARK 3 STRUCTURE WAS THEN ENERGY REMARK 3 MINIMIZED. THE X-RAY REMARK 3 COORDINATES OF T.
