a, Genomic context of the bacterial actin-related protein (BARP) gene within the genome of the marine Deltaproteobacterium H. ochraceum. Red, gene encoding BARP; white, genes encoding hypothetical proteins; black, genes with functional annotations. b, RT–PCR demonstration of expression of the gene encoding BARP in H. ochraceum.c, Ribbon plot of the putative structure of BARP. d, Alignment of BARP with actin from Dictyostelium discoideum29 with similarities in black shaded text. Secondary structure elements (arrows, beta-strands; bars, alpha-helices) are colour-coded as in c. A phylogenetic tree including this protein is in Supplementary Figure 1.
