Data obtained using TatP 1.0 Figure 1 Alignment and learn more GC-profiles of the genomes of D. hafniense DCB-2 and D. hafniense Y51. Alignment of the two genomes, shown with colored blocks of DNA and connecting lines, was performed by using Mauve v 2.3.1 with a view of 24 LCBs (locally collinear blocks). The lines between the genomes indicate the homologous regions in each genome. Translocation of a 1.22 mb DNA segment is seen as two contiguous blocks colored purple and green. Two transposase genes found next to the 1.22 mb DNA segment are indicated as red triangles. Positions of reductive dehalogenase (Rdh) operons in each genome are indicated. The two outer panels show the corresponding GC profiles of the two genomes, depicted as compositionally distinct domains. The profiles were

obtained by using GC-Profile https://www.selleckchem.com/products/pexidartinib-plx3397.html program which was developed based on a segmentation algorithm and cumulative GC profile technique. The genome of D. hafniense Y51 was reported to have the most uneven lengths of chromosome arms which result from the bidirectional replication of a circular chromosome at the replication origin. Based on its GC skew plot [(G-C)/(G+C)], the Y51 genome is predicted

to have the lagging strand (negative GC-skew value) roughly twice as long as the leading strand (positive GC-skew value) [9]. In contrast, the DCB-2 genome had a slightly longer leading strand (the ratio of 1.3:1). Alignment of the two genomes revealed that a translocation of a 1.22 Mb DNA segment accounted for the GC skew difference Oxymatrine (Figure 1). The immediate junctions of this segment were identified by an IS116/IS110/IS902 family transposase gene (Dhaf_0814) in DCB-2 and an IS4 family transposase gene (DSY3435) in Y51 (Figure 1), strongly implicating these insertion sequences in the translocation. The GC content profiles obtained by a segmentation algorithm show that the D. hafniense Y51 genome contains broader regions of PI3K inhibitor unusually low GC content, which appear to be occupied by prophage genomes and horizontally transferred sequences of unknown origin (Figure 1). Carbon metabolism The D. hafniense DCB-2 genome encodes genes for functional glycolysis, gluconeogenesis, and pentose phosphate pathways. The genome lacks the alternate Entner-Doudoroff pathway for glucose breakdown, which is used by many Gram-negative aerobic bacteria and Archaea [12].
