Solvation Induction of Free Energy Barriers of Decarboxylation Reactions in Aqueous Solution from Dual-Level QM/MM Simulations

open access: yesJACS Au, 2021
Carbon dioxide capture, corresponding to the recombination process of decarboxylation reactions of organic acids, is typically barrierless in the gas phase and has a relatively low barrier in aprotic solvents.

Alginate degrading enzymes: an updated comprehensive review of the structure, catalytic mechanism, modification method and applications of alginate lyases

open access: yesCritical Reviews in Biotechnology, 2021
Alginate, a kind of linear acidic polysaccharide, consists of α-L-guluronate (G) and β-D-mannuronate (M). Both alginate and its degradation products (alginate oligosaccharides) possess abundant biological activities such as antioxidant activity ...

La L-glutamate-1-carboxy-lyase des Pervenches indigènes [PDF]

open access: yesBulletin de la Société Botanique de France, 1975
ResumeLes variations de l'acide glutamique et de l'acide γ;-aminobutyrique libres au cours de la vegetation ne sont pas directement superposables a celles de l'activite de la glutamate decarboxylase. Ces dernieres sont dues aux variations de la synthese de l'enzyme.

Inhibition of Glutamic Acid Carboxy-Lyase by Alanosine

open access: yesExperimental Biology and Medicine, 1968
SummaryAlanosine is an inhibitor of glutamic acid carboxy-lyase (C-L) of bacterial origin, but not of those from squash and rat brain. Its action is competitive in respect to glutamic acid, but noncompetitive in respect to pyridoxal phosphate. Other bacterial amino acid C-L's tested, while sensitive to hydroxylamine, are not inhibited by alanosine.

UDP-glucuronate carboxy-lyase in cultured chondrocytes.

open access: yesJournal of Biological Chemistry, 1977
UDP-glucuronate carboxy-lyase has been demonstrated in chick chondrocytes in tissue culture. It occurs in the particulate fraction, and its activity is stimulated by exogenous NAD. The enzyme is allosterically activated by UDP-glucuronate and inhibited by UDP-xylose, n Values of 2.8 indicate positive cooperativity of at least three interacting sites on

Porphyrin biosynthesis. VII. Porphyrinogen carboxy-lyase from avian erythrocytes. Purification and properties [PDF]

open access: yesBiochimica et Biophysica Acta (BBA) - Enzymology, 1970
1. Uroporphyrinogen carboxy-lyase (EC 4.1.1.d), the enzyme catalysing the decaroxylation of uroporphyrinogen to coproporphyrinogen, has been isolated from normal chicken erythrocytes. The enzyme was purified 220-fold with a yield of 24% from haemolysate supernatant by DEAE-cellulose batch treatment, (NH4)2SO4 fractionation and chromatography on DEAE ...

Characterization of different alginate lyases for dissolving Pseudomonas aeruginosa biofilms

open access: yesScientific Reports, 2020
Aggregates of Pseudomonas aeruginosa form a protective barrier against antibiotics and the immune system. These barriers, known as biofilms, are associated with several infectious diseases. One of the main components of these biofilms is alginate, a homo-

The C-terminus hot spot region helps in the fibril formation of bacteriophage-associated hyaluronate lyase (HylP2)

open access: yesScientific Reports, 2015
The bacteriophage encoded hyaluronate lyases (HylP and HylP2) degrade hyaluronan and other glycosaminoglycans. HylP2 forms a functional fibril under acidic conditions in which its N-terminus is proposed to form the fibrillar core, leading to nucleation ...
