Figure 7From: The role of actin isoforms in somatic embryogenesis in Norway spruceMultiple alignments of latrunculin-binding region of a rabbit actin and four spruce actin isoforms. Threonin T186 and arginin R210 directly binding latrunculin are framed with rectangles; aspartic acid D187 and arginin R206 forming a salt bridge (indicated by arrows) are highlighted in dark gray; a loop moving under Lat B binding is in light gray, amino acid exchanges between the rabbit actin sequence and spruce isoforms are in bold. The amino-acid exchange D187→A187 in isoform 3, hypothetically responsible for altered latrunculin binding, is underlined.Back to article page
