Interfacial molecular interactions of cellobiohydrolase Cel7A and its variants on cellulose

open access: yesBiotechnology for Biofuels, 2020
Background Molecular-scale mechanisms of the enzymatic breakdown of cellulosic biomass into fermentable sugars are still poorly understood, with a need for independent measurements of enzyme kinetic parameters.

Soluble protein analog selection engine (SPASE): An automated AI‐powered server to improve protein engineering workflows

open access: yesProtein Science, Volume 35, Issue 9, September 2026.
Abstract The design of proteins with desired biophysical properties, such as high solubility and low aggregation propensity, is crucial for various biotechnological and biomedical applications. While deep learning‐based methods like ProteinMPNN have shown remarkable success in protein sequence design, their direct output may not always exhibit optimal ...

Liquid assays of endoglucanase, β-glucosidase, and cellobiohydrolase.

open access: yes, 2014
Reducing sugars released from CMC (endoglucanase activity) and Avicel (β-glucosidase activity) when treated with fungal filter paper culture supernatant and p-nitrophenol release from pNPβG (cellobiohydrolase activity). Tests were performed in triplicate,

Limited evidence for soil enzyme activities mediating C:N discrepancies between microbial biomass and organic matter in year 145 of a maize‐based agroecosystem experiment

open access: yesSoil Science Society of America Journal, Volume 90, Issue 5, September/October 2026.
Abstract Soil microbial biomass (MB) generally exhibits a narrower C:N than soil organic matter (SOM), creating a stoichiometric discrepancy hypothesized to be reconciled in part by C‐ and N‐acquiring enzyme activities. We used soils from an at‐equilibrium long‐term experiment to evaluate the degree to which MB C:N plasticity and enzyme activities ...

Hypocrea jecorina Cellobiohydrolase I Stabilizing Mutations Identified Using Noncontiguous Recombination [PDF]

open access: yes, 2013
Noncontiguous recombination (NCR) is a method to identify pieces of structure that can be swapped among homologous proteins to create new, chimeric proteins. These “blocks” are encoded by elements of sequence that are not necessarily contiguous along

Transcriptome and Zymogram Analyses Reveal a Cellobiose-Dose Related Reciprocal Regulatory Effect on Cellulase Synthesis in Cellulosilyticum ruminicola H1

open access: yesFrontiers in Microbiology, 2017
The rumen bacterium Cellulosilyticum ruminicola H1 efficiently hydrolyzes cellulose. To gain insights into the regulatory mechanisms of cellulase synthesis, comparative transcriptome analysis was conducted for cultures grown on 2% filter paper, 0.5 and 0.

Soil carbon stocks, microbial stoichiometry, and enzyme activities across a 54‐year chronosequence of continuous maize versus maize–soybean rotations

open access: yesSoil Science Society of America Journal, Volume 90, Issue 5, September/October 2026.
Abstract Crop rotational diversity is hypothesized to enhance soil organic carbon (SOC) surface stocks, yet the long‐term SOC response to maize (Zea mays L.)–soybean [Glycine max (L.) Merr.] (MS) relative to continuous maize (MM) is inconsistent despite the greater residue C inputs in MM.

Effects of polystyrene nanoparticles on the microbiota and functional diversity of enzymes in soil

open access: yesEnvironmental Sciences Europe, 2018
Background The increasing production of nanoplastics and the fragmentation of microplastics into smaller particles suggest a plausible yet unclear hazard in the natural environment, such as soil.

Cropping system and nitrogen fertilization modulate soil enzyme kinetics

open access: yesSoil Science Society of America Journal, Volume 90, Issue 5, September/October 2026.
Abstract The decomposition of soil organic matter and nutrient cycling are largely mediated by extracellular enzymes, yet the effect of soil management on enzyme kinetic (Michaelis constant [Km] and maximum velocity [Vmax]) remains poorly understood.

Co-fermentation using Recombinant Saccharomyces cerevisiae Yeast Strains Hyper-secreting Different Cellulases for the Production of Cellulosic Bioethanol

open access: yesScientific Reports, 2017
To realize the economical production of ethanol and other bio-based chemicals from lignocellulosic biomass by consolidated bioprocessing (CBP), various cellulases from different sources were tested to improve the level of cellulase secretion in the yeast
