Interconnectivity between Surface Reactivity and Self-Assembly of Kemp Elimination Catalyzing Nanorods
Shandilya, Ekta,Dasgupta, Basundhara,Maiti, Subhabrata
, p. 7831 - 7836 (2021)
Understanding the fundamental facts behind dynamicity of catalytic processes has been a longstanding quest across disciplines. Herein, we report self-assembly of catalytically active gold nanorods that can be regulated by tuning its reactivity towards a p
Catalysis of the Kemp elimination by antibodies elicited against a cationic hapten
Genre-Grandpierre, Arnaud,Tellier, Charles,Loirat, Marie-Jeanne,Blanchard, Dominique,Hodgson, David R.W.,Hollfelder, Florian,Kirby, Anthony J.
, p. 2497 - 2502 (1997)
Rather efficient catalysis of the decomposition of 5-nitro-benzisoxazole to the cyanophenol was observed with antibodies elicited against a cationic hapten structurally unrelated to the benzisoxazole substrate. The rate enhancement by the most active anti
Vesicles accelerate proton transfer from carbon up to 850-fold
Perez-Juste, Jorge,Hollfelder, Florian,Kirby, Anthony J.,Engberts, Jan B. F. N.
, p. 127 - 130 (2000)
(equation presented) We have analyzed the different catalytic effects of surfactant aggregates upon the rate-determining hydroxide ion induced deprotonation reaction of 1. Vesicles are more effective catalysts than micelles, most likely providing a more a
Superior Proton-Transfer Catalytic Promiscuity of Cytochrome c in Self-Organized Media
Rani, Sheetal,Dasgupta, Basundhara,Bhati, Gaurav Kumar,Tomar, Kalpana,Rakshit, Sabyasachi,Maiti, Subhabrata
, p. 1285 - 1291 (2021)
Evolutionarily elderly proteins commonly feature greater catalytic promiscuity. Cytochrome c is among the first set of proteins in evolution to have known prospects in electron transport and peroxidative properties. Here, we report that cyt c is also a pr
Investigation of medium effects in a family of decarboxylase antibodies
Tarasow,Lewis,Hilvert
, p. 7959 - 7963 (1994)
A family of naphthalenedisulfonate-binding antibodies catalyze the decarboxylation of 5-nitro-3-carboxybenzisoxazole, providing a series of structurally similar catalysts for investigating the influence of protein microenvironment on reactivity. Eight rep
Mechanistic study of proton transfer and hysteresis in catalytic antibody 16E7 by site-directed mutagenesis and homology modeling
Zheng, Lei,Manetsch, Roman,Woggon, Wolf-Dietrich,Baumann, Ulrich,Reymond, Jean-Louis
, p. 1021 - 1029 (2005)
Antibody 16E7 catalyzes the carbon protonation of enol ether 2 to hemiacetal 3, and the carbon deprotonation of benzisoxazole 7 to phenol 8. This antibody shows an extreme case of hysteresis, requiring several hours to reach full activity. Antibody 16E7 w
Design of a switchable eliminase
Korendovych, Ivan V.,Kulp, Daniel W.,Wu, Yibing,Cheng, Hong,Roder, Heinrich,DeGrado, William F.
, p. 6823 - 6827 (2011)
The active sites of enzymes are lined with side chains whose dynamic, geometric, and chemical properties have been finely tuned relative to the corresponding residues in water. For example, the carboxylates of glutamate and aspartate are weakly basic in w
Characterization of proton-transfer catalysis by serum albumins
Hollfelder, Florian,Kirby, Anthony J.,Tawfik, Dan S.,Kikuchi, Kazuya,Hilvert, Donald
, p. 1022 - 1029 (2000)
Two independent investigations of catalysis by BSA and other serum albumins are combined to provide detailed insight into the mechanism of a classical proton-transfer reaction taking place on the surface of a protein. The Kemp elimination involves the gen
Catalysis of the Kemp elimination by natural coals
Shulman, Hagit,Keinan, Ehud
, p. 3747 - 3750 (2000)
(matrix presented) Commercially available coals were found to be efficient heterogeneous catalysts of the Kemp elimination reaction in aqueous solutions. A pH-rate profile study suggests that catalysis originates from specific catalytic groups and not sim
Influence of water-soluble pillararene hosts on Kemp elimination
Hu, Xiao-Yu,Huang, Xingyi,Liu, Qian,Shen, Yuhong,Tian, Xueqi,Wang, Kaiya
, p. 38115 - 38119 (2021/12/09)
Since pillar[5]arene was first discovered in 2008, it has developed into a multifunctional supramolecular host. Its application covers many fields from drug delivery and chemical sensing to the construction of molecular machines, and so on. Supramolecular
