Near complete copies of Tn4371-like https://www.selleckchem.com/products/azd1080.html elements were also found in Burkholderia ambifaria AMMD and Burkholderia multivorans ATCC17616, where both were found to lack the Tn4371-like integrase gene suggesting that the elements may no longer be mobile. New elements were also found in Ralstonia solanacearum MolK2 and a second element in Diaphorobacter sp. TPSY, these share similarities in the stabilisation and transfer regions of the element to Tn4371-like elements

but they have a different integrase region not related to the int Tn4371 gene. All of the elements reported here [Table 1 and 2] appear to share a common scaffold or backbone that is approximately 24 kb in size containing a 1.5 kb integrase gene; an 8.5 kb replication/stability gene cluster and a 14 kb conjugal transfer/mating pair formation cluster [Fig. 1]. A visual representation of this can

be seen in Figs. 2, 3, 4 and 5 where the various sequences were aligned for comparison, the core scaffold identified and ‘adaptive’ genes highlighted which vary from element to element. Figure 2 Use of the Artemis comparison tool to analysis Tn 4371 -like ICE sequences 3-MA chemical structure of Tn 4371, R. pickettii 12J, both elements from D. acidovorans SPH-1 and C. testosteroni KF-1. All ICEs analysed shared extensive sequence homology, and general gene order. Arrows on top delimit the functional regions whose order is well conserved in all Tn4371-like ICEs. Figure 3 Use of the Artemis comparison tool to analysis Tn 4371 -like ICE sequences of Tn 4371, P. aeruginosa 2192, P. aeruginosa PA7, P. aeruginosa UCBPP-PA14 and P. aeruginosa AZD1152 solubility dmso PACS171b. All ICEs analysed shared extensive sequence homology,

and general gene order. Arrows on top delimit the functional regions whose order is well conserved in all Tn4371-like ICEs. Figure 4 Use of the Artemis comparison tool to analysis Tn 4371 -like ICE sequences of Tn 4371, Shewanella sp. ANA-3, C. litoralis KT71, S. maltophilia K279a and Thioalkalivibrio sp. HL-EbGR7. All ICEs analysed shared extensive sequence click here homology, and general gene order. Arrows on top delimit the functional regions whose order is well conserved in all Tn4371-like ICEs. Figure 5 Use of the Artemis comparison tool to analysis Tn 4371 -like ICE sequences of Tn 4371, A. avenae subsp. citrulli AAC00-1, Acidovorax sp. JS42, B. petrii DSM12804, Diaphorobacter sp. TPSY and P. naphthalenivorans CJ2 plasmid pPNAP01. All ICEs analysed shared extensive sequence homology, and general gene order. Arrows on top delimit the functional regions whose order is well conserved in all Tn4371-like ICEs. Bioinformatic comparisons were performed between the genes that make up the core scaffold region of the ICE and these ranged from the highly conserved traG gene, with 84 to 96% aa identity, trbE gene, with 76 to 94% aa identity, and the parA gene, with 90 to 97% aa identity, to the less-conserved traR gene, with 53 to 84% aa identity.
