Assay methods for pectic enzymes
TL;DR: Three assay procedures are described that permit quantitative assay of hydrolytic and β-eliminative pectic enzymes, respectively, and can guide purification strategies, particularly when used in conjunction with titration curves.

Soluble chromogenic substrates for the assay of endo-1,4-beta-xylanases and endo-1,4-beta-glucanases
TL;DR: New soluble chromogenic substrates were prepared for specific and rapid assays of endo-1,4-beta-xylanases and endo -1, 4- beta-glucanases, advantageous for rapid analyses of large amount of samples and also permit evaluation of the activities of both enzymes in the presence of exo-Beta-glycanases and beta-glycosidases.

Cooperativity of Esterases and Xylanases in the Enzymatic Degradation of Acetyl Xylan
TL;DR: It is demonstrated that fungal esterase and xylanase activities act cooperatively in hydrolyzing acetyl xylan, and that the two activities also act synergistically to liberate acetyl residues.

Structure of the Linkage Region between the Polysaccharide and Protein Parts of Saccharomyces cerevisiae Mannan
TL;DR: The observation that this kind of branched inner core structure is made in a yeast mutant that forms an unbranched outer chain demonstrates that the formation of these two parts of the molecule is regulated in part by different enzymes and may serve different functions in the translocation of the mannan proteins and their organization in the cell wall.

Physiological Effects of Gibberellic Acid. II. On Starch Hydrolyzing Enzymes of Barley Endosperm
TL;DR: Evidence is presented of the production of reducing sugars and an increase in amylase activity resulting from the treatment of barley endosperm with GA, and the suggestion that an endogenous gibberellin, such as that present in germinating barley, might, in fact, play an important hormonal role during the germination process.
