Proteins, proteins everywhere [PDF]

open access: yesScience, 2021
The first protein structures were determined by x-ray crystallography in 1957 by John C. Kendrew and Max F. Perutz. As a bioinorganic chemist, I was delighted that the structures were myoglobin and hemoglobin, both heme proteins with big, beautiful iron atoms.

Annotation and Curation of the Protein Data Bank [PDF]

open access: yes, 2009
The Protein Data Bank (PDB) is the worldwide repository for experimentally determined 3D structures of biological macromolecules. Established in 1971 with just seven structures, it presently includes more than 56,000 entries.

Directed evolution converts subtilisin E into a functional equivalent of thermitase [PDF]

open access: yes, 1999
We used directed evolution to convert Bacillus subtilis subtilisin E into an enzyme functionally equivalent to its thermophilic homolog thermitase from Thermoactinomyces vulgaris.

Contextualized Protein-Protein Interactions [PDF]

open access: yesPatterns, 2021
Protein-protein interaction (PPI) databases are an important bioinformatics resource, yet existing literature-curated databases usually represent cell-type-agnostic interactions, which is at variance with our understanding that protein dynamics are context specific and highly dependent on their environment.

Application of fourier transform and proteochemometrics principles to protein engineering

open access: yesBMC Bioinformatics, 2018
Background Connecting the dots between the protein sequence and its function is of fundamental interest for protein engineers. In-silico methods are useful in this quest especially when structural information is not available.

Multiple structural alignment for distantly related all b structures using TOPS pattern discovery and simulated annealing [PDF]

open access: yes, 2003
Topsalign is a method that will structurally align diverse protein structures, for example, structural alignment of protein superfolds. All proteins within a superfold share the same fold but often have very low sequence identity and different biological

Computationally designed variants of Escherichia coli chorismate mutase show altered catalytic activity [PDF]

open access: yes, 2005
Computational protein design methods were used to predict five variants of monofunctional Escherichia coli chorismate mutase expected to maintain catalytic activity.

Cryo-EM structure of a catalytic amyloid fibril

open access: yesScientific Reports, 2023
Catalytic amyloid fibrils are novel types of bioinspired, functional materials that combine the chemical and mechanical robustness of amyloids with the ability to catalyze a certain chemical reaction.

Under Conditions of Amyloid Formation Bovine Carbonic Anhydrase B Undergoes Fragmentation by Acid Hydrolysis

open access: yesBiomolecules, 2021
The development of many severe human diseases is associated with the formation of amyloid fibrils. Most of the available information on the process of amyloid formation has been obtained from studies of small proteins and peptides, wherein the features ...
