Xylan inhibition of cellulase binding and processivity observed at single-molecule resolution

This study uses single-molecule microscopy to show that xylan inhibits cellulase binding and processivity on cellulose fibrils, highlighting the need for xylan removal in biomass processing.

Lignin impairs Cel7A degradation of cellulose by impeding enzyme movement and not by acting as a sink

This study uses single-molecule fluorescence microscopy to show that lignin impairs Cel7A degradation of cellulose by blocking access and hindering enzyme movement, rather than acting as a sink.

Single-molecule tracking reveals dual front door/back door inhibition of Cel7A cellulase by its product cellobiose

This study uses single-molecule tracking to show that cellobiose inhibits Cel7A cellulase by binding to both the product release site and the substrate binding tunnel.

Hydrogen peroxide modulates lignin and silica deposits in sorghum roots

The paper investigates how hydrogen peroxide modulates lignin and silica deposits in sorghum roots, finding that H2O2 regulates lignin deposition but not its patterning.
