Fig. 6. Multiple alignment of a putative zinc finger in pushover/calossin and two archaeal proteins. Conserved cysteines predicted to bind Zn2+ are shown as white-on-black. Annotation of this alignment is as Fig. 4. Species abbreviations as Figs. 4 and 5, except ARCFU, Archaeoglobus fulgidus METJA, Methanococcus jannaschii.
