The cat genes G hypothesis that it {should be|ought to be|needs to encode the proteins responsible for catechol degradation and are organized in two clusters [catRBCA (T1E_5502 through T1E_5505) and catBCA (T1E_1744 via T1E_ 1746)] (Fig. The genes that encoded the enzymes of those two pathways had been identified according to BLAST evaluation and comparison to proteins that carry out the indicated reactions.3 enzymes, homogentisate dioxygenase (T1E_1557), a newly identified putative maleylacetoacetate isomerase (T1E_1555) and fumarylacetoacetate hydrolase (T1E_1558). In this pathway homogentisate is funnelled to yield fumarate and acetoacetate. A look for hpa and gtd genes that encode genes belonging to the homoprotocatechuate and gentisate pathways yielded no results in the DOT-T1E genome, which suggests the absence of a meta ring-cleavage pathway for the degradation of homoprotocatechuate and gentisate. Pseudomonads strains are capable to use a selection of inorganic nitrogen sources. Within this regard 3 predicted transporters involved in the uptake of ammonium had been identified. T1E incorporates ammonium into C skeletons applying primarily the ATP-dependent activity of glutamine synthetase (GS) followed by the action of glutamate synthase (GOGAT). The genome of T1E encodes 4 GS (T1E_0118, 1260, 2050 and 4444) and four GOGAT enzymes (T1E_1644, 2053, 2506 and 3293). Strain T1E can use nitrate as an N supply, that is lowered to ammonium employing an assimilatory nitrate reductase (EC: 1.7.99.four) encoded by the T1E_4793 gene, that may be within a cluster with nirB and nirD which encode an assimilatory nitrite reductase (EC1.7.1.4).Teria. This pathway consists of a catechol branch (cat) and protocatechuate branch (pca). The pca genes in P. putida DOT-T1E are arranged in 3 operons [pcaRKFTBDC (T1E_0230 through T1E_0238), pcaGH (T1E_0829 and T1E_830), pcaJI (T1E_2058 and T1E_2059)], as is also the case in other P. putida and P. syringae strains (Fig. S5). The cat genes encode the proteins responsible for catechol degradation and are organized in two clusters [catRBCA (T1E_5502 by means of T1E_5505) and catBCA (T1E_1744 by means of T1E_ 1746)] (Fig. S6), maintaining the gene order found in other folks P. putida strains as well as in P. aeruginosa. The identity in the catBC plus a genes in both clusters is inside the array of 79?two . Also, we should really mention that two other catA genes had been identified, one particular of them with a higher degree of similarity for the KT2440 catA2 gene, which corresponded to ORF T1E_1057, that is adjacent for the benRABCDK genes (T1E_1055 to T1E_1064) for benzoate degradation; though the other catA allele corresponded to ORF T1E_5511. It really should be noted that this allele is within a cluster of genes which might be transcribed within the exact same path and which encode genes for salycilate metabolism (T1E_5510 by means of T1E_5513). The genes involved in phenylacetate degradation were also identified in P. putida DOT-T1E. There are actually 16 genes encoding for phenylacetate degradation organized within a cluster (ORFs T1E_5587 to T1E_5603) and within the cluster a series of potential operons have been identified, i.e. the paaGHIJK genes (T1E_5590 by way of T1E_5594) that encode the ring-hydroxylating oxygenase enzyme, the paaABCDE genes that encode the b-oxidation enzymes, a possible phenylacetate transport program (paaLM) and the regulatory method produced of paaXY, that correspond to T1E_5587 and T1E_5588 respectively. Homologous genes for degradation of homogentisate are also present in strain DOT-T1E. Homogentisate is catabolized by a central catabolic pathway that involvesFig. 4.
