Mechanism of Reconstitution/Activation of the Soluble PQQ-Dependent Glucose Dehydrogenase from Acinetobacter calcoaceticus: A Comprehensive Study [PDF]

open access: yesACS Omega, 2019
The ability to switch on the activity of an enzyme through its spontaneous reconstitution has proven to be a valuable tool in fundamental studies of enzyme structure/reactivity relationships or in the design of artificial signal transduction systems in ...

Crystal structure of a calcium(II)–pyrroloquinoline quinone (PQQ) complex outside a protein environment

open access: yesActa Crystallographica Section C Structural Chemistry, 2020
Pyrroloquinoline quinone (PQQ) is an important cofactor of calcium- and lanthanide-dependent alcohol dehydrogenases. The crystal structure of a Ca–PQQ complex (Ca3PQQ2·13H2O) is reported for the first time outside a protein environment.

IR-Improved DGLAP Theory

open access: yes, 2005
We show that it is possible to improve the infrared aspects of the standard treatment of the DGLAP evolution theory to take into account a large class of higher order corrections that significantly improve the precision of the theory for any given level ...

Genetic Impacts on the Structure and Mechanics of Cellulose Made by Bacteria

open access: yesAdvanced Science, Volume 12, Issue 33, September 4, 2025.
A genetic mutation in a protease of a cellulose‐overproducing evolved bacterium significantly affects the proteome, structure, and mechanical properties of bio‐fabricated cellulose pellicles. By overexpressing synthase proteins that build the cellulose‐forming biological machinery of the cell, the evolved bacterium generates dense, stiff, and strong ...

Interactions of rare earth elements with living organisms and emerging biotechnical applications

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 5, Page 1251-1274, September 2025.
Rare earth elements (REEs) are critical resources required to achieve net‐zero carbon emission targets and energy security. However, rising demand for REEs coupled with significant extraction and processing challenges and geopolitical risks restricts access to REE resources.

Exploring the Bacterial Microbiota of Seeds

open access: yesMicrobial Biotechnology, Volume 18, Issue 9, September 2025.
The presence of a functional bacterial microbiota in seeds is well established. However, the mechanisms underlying microbial entry into the propagule and its intracellular compartments remain largely unresolved. ABSTRACT The seed microbiota, a still underexplored component of plant–microbe interactions, plays a pivotal role in plant development and ...
