A common functional conformational change has been reported in this protein family, which involves switching from an open form to a sugar-transporter bindable form, ... [11,15]. A common drastic conformational change is found in this protein family, which participates in switching from an open form to a closed form [16]. In EcoMBP, the closed form has been obs...
