TLDR
In a commercial pectinase preparation, an enzyme was found which attacked only the methyl ester of pectic acid as mentioned in this paper, which indicated the presence of Δ-4,5 unsaturated galacturonic acid groups.Abstract:
In a commercial pectinase preparation an enzyme has been found which attacks only the methyl ester of pectic acid. A study of the breakdown products by ultraviolet absorption, ozonation and reaction with thiobarbituric acid indicated the presence of Δ-4,5 unsaturated galacturonic acid groups.read more

Degradation of Plant Cell Walls and Membranes by Microbial Enzymes
D. F. Bateman,H. G. Basham +1 more
TL;DR: Understanding of cell wall and membrane structure, coupled with knowledge of the enzymes capable of degrading the components of these structures, and an analysis of the association of these enzymes with diseased tissue, should enable us to make an appraisal of their involvement in pathogenesis.

Polysaccharide lyases
TL;DR: A review of the sources, regulation, purification, and properties of these polysaccharide eliminases can be found in this paper, with a focus on enzymes of microbial origin.

Structure of the Aspergillus niger pelA gene and its expression in Aspergillus niger and Aspergillus nidulans.
TL;DR: The complete nucleotide sequence of the pectin lyase PLA-encoding gene pelA has been determined and it is shown that the proteins share 69% amino acid identity.

Extracellular and intracellular polygllacturonic acid trans-eliminases of Erwinia carotovora.
TL;DR: From the cells of the same organism, an intracellular enzyme wag isolated which has properties similar to those of the extra-cellular polygalacturonic acid trans-eliminase was purified from the culture fluid of Erwinia carolovora.

The Enzymatic Degradation of Heparin and Heparitin Sulfate III. PURIFICATION OF A HEPARITINASE AND A HEPARINASE FROM FLAVOBACTERIA
Peter Hovingh,Alfred Linker +1 more
TL;DR: In agreement with previous data both enzymes act as eliminases rather than hydrolases yielding products containing Δ4,5-unsaturated uronic acid.

Über den alkalischen Pektinabbau
TL;DR: In this paper, it was shown by osmometric molecular weight determinations that the alkaline deesterification of pectin is accompanied by a strong depolymerisation, and this too, even if the saponification is made in a pure N2-atmosphere.
