Polysaccharide lyases are the products of various microorganisms, bacteriophage and some eukaryotes. All such enzymes cleave a hexose-1,4-alpha- or beta-uronic acid sequence by beta-elimination. They are in some examples, the only known type of enzymes degrading their polyanionic substrates.

Conformational gating in ammonia lyases [PDF]
ABSTRACTAmmonia lyases (AL) are enzymes of industrial and biomedical interest. Knowledge of AL structure-dynamics-function relationship would be instrumental for making use of the application potential of these enzymes. We investigated, using microsecond molecular dynamics, the conformational changes in the proximity of the catalytic pocket of a 3 ...

Two pectate lyase genes (Bx-pel-1 and Bx-pel-2) were cloned from the pine wood nematode, Bursaphelenchus xy-lophilus. The deduced amino acid sequences of these pectate lyases are most similar to polysaccharide lyase family 3 proteins.

Novel Pectate Lyase Genes of Heterodera glycines Play Key Roles in the Early Stage of Parasitism. [PDF]
Pectate lyases are known to play a key role in pectin degradation by catalyzing the random cleavage of internal polymer linkages (endo-pectinases). In this paper, four novel cDNAs, designated Hg-pel-3, Hg-pel-4, Hg-pel-6 and Hg-pel-7, that encode pectate

Predictive modelling of the combined effect of temperature and water activity on the in vitro growth of Erwinia spp. infecting potato tubers in Belgium [PDF]
Erwinia carotovora ssp. atroseptica (Eca), Erwinia carotovora ssp. carotovora (Ecc) and Erwinia chrysanthemi (Ech), are the main cause of potato tuber decay (soft rot) in storage and stem rot in the field (blackleg). The bacteria are characterized by the

The Kinetics of Adenylosuccinate Lyase
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.

Maize Phenylalanine Ammonia-Lyase Has Tyrosine Ammonia-Lyase Activity [PDF]
Abstract A full-length cDNA encoding phenylalanine ammonia-lyase (PAL) from Zea mays L. was isolated and the coding region was expressed in Escherichia coli as a C-terminal fusion to glutathione S-transferase. After purification by glutathione-Sepharose chromatography, the glutathione S-transferase moiety was cleaved off and the ...
