Identified as much as 1751 enzymatic reactions performed by around 1686 enzymes with 1268 special prospective substrates. A numerical classification for the enzymes depending on the chemical reactions they carried out in accordance with the Enzyme Commission quantity (EC quantity) was elaborated in an Digitoxin site effort to recognize the metabolic potential of this strain. According to EC nomenclature (Bairoch, 2000), oxidoreductases (EC 1) had been by far the most abundant enzymes, representing 41 from the total (Fig. 3A).

Pseudomonas putida DOT-T1E chromosome GC Skew analysis. Gen Skew is defined as the normalized excess of G over C within a offered sequence. It truly is offered by (G-C)/(G+C), and it can be calculated using a sliding window of 1000 nucleotides along the genome. It is represented in blue. The cumulative GC-skew would be the sum of the values of neighbouring sliding windows from an arbitrary start to a given point in the sequence and it really is represented in red. GC-skew is optimistic in the leading strand and unfavorable within the lagging strand.(transferases), EC classes 3 (hydrolases) and four (lyases) represented 21 , 17 and 10 of all enzymes respectively, even though isomerases (EC five) and ligases (EC 6) were the least abundant, with 5 and six of total enzymes respectively. That is constant together with the situation of a higher metabolic versatility described for Pseudomonads (Daniels et al., 2010; Palleroni, 2010). The second degree of EC nomenclature (EC X.X) contains a total of 65 subclasses, of which 51 are present in P. putida DOT-T1E (Fig. 3B). As expected, from the high quantity of oxidoreductases, two subclasses of this group have been amongst one of the most abundant with enzymes that use the CH-OH group as donor (EC 1.1) and those utilizing aldehyde as donors (EC 1.2) representing almost 12 with the total for each group. A striking observation was the presence of particular abundant enzyme classes, for instance for example phosphotransferases (EC 2.7, 7 of total); plus a series of hydrolases acting on carbon-nitrogen bonds (EC three.five, 5 of total), or acting on ester bonds and anhydrides (EC three.1; about 5 of total). Figure 3B presents the enzymes of DOT-T1E grouped according to their subclasses. We additional classified the enzymes identified in functional subclasses in accordance with the EC X.X.X nomenclature to concentrate around the possible donors and acceptors in the case of oxidoreductase enzymes or potentialgroups of substrates in other enzymes (Fig. 3C). Amongst a total quantity of 269 subclasses inside the third level of EC nomenclature (EC X.X.X), 150 were present in P. putida DOT-T1E. Oxidoreductases making use of aldehydes as donor groups with NAD+ or NADP+ as acceptor (EC 1.two.1) had been the most abundant (11 of the total), also numerically crucial have been the carbon-oxygen lyases (EC four.2.1, 4 of total), nucleotidyl phosphotransferases (EC 2.7.7, three of total) and acyltransferases (EC two.3.1, 3 of total). Working with the Pathway Tool platform, the set of phenomics assays previously described by our group (Daniels et al., 2010), as well as the EC X.X.X classification permitted us to explain the pattern of Licochalcone A site development of strain DOT-T1E with 65 unique carbon sour.
