Characterization of α- Amylase Produced from a Local Isolate of Bacillus licheniformis R5 [PDF]

Al-Qadisiyah Journal For Agriculture Sciences, 2016
This research is conducted at the College of Agriculture, University of Baghdad in 2004. The characterization of the purified enzyme shows that the molecular weight of the enzyme produced from the bacteria is 56.000 Daltons as it was determined by gel ...

Enzyme activity below the dynamical transition at 220K [PDF]

, 1998
Enzyme activity requires the activation of anharmonic motions, such as jumps between potential energy wells. However, in general, the forms and time scales of the functionally important anharmonic dynamics coupled to motion along the reaction coordinate ...

Decoding the dynamic extracellular matrix in cancer—3D models and bioscaffolds rewire the rules of tumor progression

FEBS Letters, EarlyView.
Cancer progression is regulated by the dynamic matrix code of the tumor microenvironment, which influences cellular behavior and disease development. Importantly, matrix remodeling in three‐dimensional cancer models more accurately reflects in vivo conditions compared to conventional two‐dimensional systems.

Expression and regulation of cyclic nucleotide phosphodiesterases in human and rat pancreatic islets. [PDF]

PLoS ONE, 2010
As shown by transgenic mouse models and by using phosphodiesterase 3 (PDE3) inhibitors, PDE3B has an important role in the regulation of insulin secretion in pancreatic β-cells. However, very little is known about the regulation of the enzyme.

Sensor potency of the moonlighting enzyme-decorated cytoskeleton [PDF]

, 2013
Background: There is extensive evidence for the interaction of metabolic enzymes with the eukaryotic cytoskeleton. The significance of these interactions is far from clear.

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

FEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Determination of enzyme activities with the enzyme thermistor unit [PDF]

FEBS Letters, 1979
Practically all enzyrnic reactions can be followed by calorimetry. Important advantages of this technique are that the optical properties of the sample do not interfere with the measurements and that no auxiliary enzymic reactions are required such as those leading to changes in optical absorption that can be followed spectrophotometrically.

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

FEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

A comparative study of enzyme immobilization strategies for multi-walled carbon nanotube glucose biosensors [PDF]

, 2011
This work addresses the comparison of different strategies for improving biosensor performance using nanomaterials. Glucose biosensors based on commonly applied enzyme immobilization approaches, including sol-gel encapsulation approaches and ...

Discerning protein pools by selective staining with self‐labeling tags

FEBS Letters, EarlyView.
Cell surface proteins have an intra‐ and extracellular pool. Combining genetic fusion to self‐labeling tags that can be addressed with small molecule fluorophores allows separating these pools. We highlight recent developments and techniques for state‐of‐the‐art interrogation of cell surface proteins in the complex tissue setting.
