A comparative study of the efficacy of alginate lyases in the presence of metal ions elevated in the cystic fibrosis lung milieu

Biochemistry and Biophysics Reports
Pseudomonas aeruginosa, a common cause of morbidity in cystic fibrosis, chronically infects the patient's lungs by forming an alginate-containing biofilm.

Characterization of a New Cold-Adapted and Salt-Activated Polysaccharide Lyase family 7 Alginate Lyase from Pseudoalteromonas sp. SM0524

Frontiers in Microbiology, 2016
Marine bacterial alginate lyases play a role in marine alginate degradation and carbon cycling. Although a large number of alginate lyases have been characterized, reports on alginate lyases with special characteristics are still rather less.

Cloning and characterization of a pectin lyase gene from Colletotrichum lindemuthianum and comparative phylogenetic/structural analyses with genes from phytopathogenic and saprophytic/opportunistic microorganisms

BMC Microbiology, 2011
Background Microorganisms produce cell-wall-degrading enzymes as part of their strategies for plant invasion/nutrition. Among these, pectin lyases (PNLs) catalyze the depolymerization of esterified pectin by a β-elimination mechanism.

Genome Analysis of a Novel Polysaccharide-Degrading Bacterium Paenibacillus algicola and Determination of Alginate Lyases

Marine Drugs, 2022
Carbohydrate-active enzymes (CAZymes) are an important characteristic of bacteria in marine systems. We herein describe the CAZymes of Paenibacillus algicola HB172198T, a novel type species isolated from brown algae in Qishui Bay, Hainan, China.

Occurrence and properties of bacterial pectate lyases [PDF]

, 1972
Some 100 pectolytic bacteria belonging to different genera and species, were obtained by isolation from vegetables and by screening of culture collections. The crude enzyme preparations of 19 of these strains were typed by mutual comparison.

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

A novel ATP dependent dimethylsulfoniopropionate lyase in bacteria that releases dimethyl sulfide and acryloyl-CoA

eLife, 2021
Dimethylsulfoniopropionate (DMSP) is an abundant and ubiquitous organosulfur molecule in marine environments with important roles in global sulfur and nutrient cycling.

The Kinetics of Adenylosuccinate Lyase

Journal of Biological Chemistry, 1968
Initial rate kinetics, product inhibition patterns, and equilibrium kinetics all indicate that cleavage of adenylosuccinate (AMP-S) by yeast adenylosuccinate lyase proceeds primarily by a reaction in which fumarate leaves the enzyme before AMP and cannot bind to free enzyme at kinetically significant concentrations.
