Sentences with phrase «high catalytic efficiency»

β - Lactamases encoded by reconstructed sequences corresponding to the GNCA node have been previously shown11 to be able to degrade a variety of antibiotics, including penicillin and third - generation antibiotics with efficiencies similar to that of a modern average enzyme (by contrast, the modern TEM - 1 β - lactamase is a specialist enzyme that displays high catalytic efficiency with penicillin and a substantially lower efficiency with third - generation antibiotics).

The structure reveals key interactions that probably contribute to the high catalytic efficiency of this enzyme relative to other flaviviruses, indicating promising starting points for drug design.

The P2 4 - aminomethylphenylalanine moiety of the inhibitor forms a salt - bridge with the nonconserved Asp83 of NS2B; ion - pairing between Asp83 and the P2 residue of the substrate likely accounts for the enzyme's high catalytic efficiency.
