Figure 6b and S3). Though RMS fluctuations for the single mutant M279N had been related to the double mutant about residues 100, 107, 121, and 131, they were improved relative to the other proteins close to residue 222. Therefore, the B domain, that is critical for substrate specificity in other GH13 enzymes, is extra mobile in both mutants [57]. The dihedral angles (1 ) on the catalytic acid-baseresidue of wild sort and mutants from Tenofovir diphosphate web TmAmyA and TmGTase had been analyzed, as elsewhere [47], and are shown in Figures S2 and S4. We observed that contrary to David et al., the 3 angle showed a extra diffuse distribution within the far more hydrolytic variants of both enzymes (wild-type TmAmyA vs. K98P/D99A/H222Q, and wild-type TmGTase vs. M279N). In addition, we observed a bigger conformational sampling with the catalytic acid-base within the much more hydrolytic variant of every pair (Figure S5). As Lundemo et al. has pointed out, the residue chain’s mobility andMolecules 2021, 26,K98P/D99A/H222Q mutant was rigidified at the loops and helices comprising residues 325, 387, and 415. The modifications in flexibility had been also studied for wild-type TmGTase against M279N single and T274V/M279N double mutants. An augmentation inside the RMSF of the double mutant T274V/M279N was evident when compared to these in the wild type TmGTase, 10 of 24 around residues 100, 107, 121 (B-domain), 131 (+2 subsite, B domain), 210 (loop 45), 222 (helix 5), 264 (helix six), and 325 (loop 45, near subsite -3; Figures 6b and S3). Though orientation may be much better described byM279Nand 2 angles. In addition, when studying RMS fluctuations for the single mutant the 1 were comparable towards the double mutant about the cyclodextrin glucosyltransferase from Bacillus stearothermophilusthe other proteins near residues 100, 107, 121, and 131, they have been enhanced relative to NO2, a GH13 enzyme, Kong et al. defined the B domain, that is critical for substrate specificity in other GH13 residue 222. As a result, a new angle for analyzing E253 within this bacillus CGTase–finding that it really is extra flexible in mutant L277M, mutants [57]. hydrolytic than the wild-type protein [66]. enzymes, is additional mobile in both that is lessFigure 6.
