A human bispecific antibody neutralizes botulinum neurotoxin serotype A

open access: yesScientific Reports, 2023
Botulinum neurotoxin (BoNT) shows high lethality and toxicity, marking it as an important biological threat. The only effective post-exposure therapy is botulinum antitoxin; however, such products have great potential for improvement. To prevent or treat

Evolutionary-scale prediction of atomic level protein structure with a language model

open access: yesbioRxiv, 2022
Artificial intelligence has the potential to open insight into the structure of proteins at the scale of evolution. It has only recently been possible to extend protein structure prediction to two hundred million cataloged proteins.

Pfam: The protein families database in 2021

open access: yesNucleic Acids Res., 2020
The Pfam database is a widely used resource for classifying protein sequences into families and domains. Since Pfam was last described in this journal, over 350 new families have been added in Pfam 33.1 and numerous improvements have been made to ...

Volatile Compounds, Fatty Acids Constituents, and Antimicrobial Activity of Cultured Spirulina (Arthrospira fusiformis) Isolated from Lake Mariout in Egypt

open access: yesThe Scientific World Journal, 2023
In this study, Arthrospira fusiformis previously isolated from Lake Mariout (Alexandria, Egypt) was cultivated in the laboratory using a medium for pharmaceutical grade Arthrospira, named as Amara and Steinbüchel medium. Hot water extract of the Egyptian

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.

Cryo-EM structure of a functional monomeric Photosystem I from Thermosynechococcus elongatus reveals red chlorophyll cluster

open access: yesCommunications Biology, 2021
Çoruh, Frank et al. report the structure of monomeric Photosystem I from cyanobacteria Thermosynechoccocus elongatus BP-1. They assign monomerization-induced loss of red chlorophylls to a cluster of chlorophylls adjacent to PsaX.

Structural mechanism of laminin recognition by integrin

open access: yesNature Communications, 2021
Recognition of laminin by integrin receptors mediates epithelial cell adhesion to basement membrane. Here, the structures of the α6β1 integrin alone and in complex with three-chain laminin-511 fragment reveal the laminin-integrin interface in molecular ...

Influence of Amino Acid Substitutions in ApoMb on Different Stages of Unfolding of Amyloids

open access: yesMolecules, 2023
To date, most research on amyloid aggregation has focused on describing the structure of amyloids and the kinetics of their formation, while the conformational stability of fibrils remains insufficiently explored.
