Figure 2From: Alkane hydroxylase genes in psychrophile genomes and the potential for cold active catalysisNMDS plots of genetic distance within four protein families (pfams). The distance between two points on the plot is proportional to their sequence similarity, thus neighboring points have similar functions. Clusters of points identified as candidate alkane hydroxylases, due to the presence of known alkane hydroxylases from Uniprot, are outlined with gray boxes.Back to article page
