Example sentences for: catalysis
How can you use “catalysis” in a sentence? Here are some example sentences to help you improve your vocabulary:
First, PfPP5 contained the catalytic core found in all Ser/Thr phosphatases of the PPP family, including the signature motifs such as GDXHGQ, GDFVDRG, RGNHE, HGLL, and SAPNYCD, to name a few [ 22 23 ] . Site-directed mutagenesis and structural studies in PP 1 and PPλ have previously established the roles of specific amino acid residues in these domains in the various aspects of catalysis, such as metal ion binding, phosphate recognition, and co-ordination of water molecules [ 24 25 26 ] .
All crystallographically characterized metallo-β-lactamases have a flexible amino acid chain that extends over the active site [ 37 42 44 45 46 47 48 49 ] . Previous NMR studies on CcrA have shown that this loop "clamps down" on substrate or inhibitor upon binding, and there is speculation that the distortion of substrate upon clamping down of the loop may drive catalysis [ 50 ] . The crystal structure of L1 showed that there is a large loop that extends over the active site, and modeling studies have predicted that two residues, Ile164 and Phe158, make significant contacts with large, hydrophobic substituents at the 2' or 6' positions on penicillins, cephalosporins, or carbapenems [ 37 ] . To test this prediction, Ile 164 and Phe158 were changed from large, hydrophobic residues to alanines to afford the I164A and F158A mutants.
The steady-state kinetic data generally support the prediction that Asn233 does not play a large role in binding or catalysis.
End-labeling of fragmented DNA was used to monitor progressive (nuclear) apoptosis [ 18 19 ] . Briefly, 3'-OH ends of DNA were linked with digoxigenin-11-d uridine triphosphate by terminal deoxynucleotidyl transferase (TdT) catalysis.
Residues of ACR1 to ACR5 of CD39 have been mutated to study the involvement of the ACR regions in catalysis.
