Geometry Concept on the Motifs of Woven Fabric in Kefamenanu Community

open access: yesJournal of Research and Advances in Mathematics Education, 2019
For the Kefamenanu community, the motif serves as the identity of the person who wears it. Nevertheless, the woven fabric must be present at cultural occasions, welcoming guests, and death ceremonies.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

First Report, Detection, and Phylogenetic Analysis of Bell Pepper Endornavirus (BPEV) Isolates Infecting Pepper in Oklahoma

open access: yesPhytoFrontiers
Peppers are a crucial source of nutrition and supplement human diets worldwide. They are of vital importance to the agricultural and food industries, especially in developing countries where growers heavily rely on the production and export of pepper. In

Understanding Hydrogen-Bond Patterns in Proteins using a Novel Statistical Model [PDF]

open access: yes, 2008
Proteins are built from basic structural elements and their systematic characterization is of interest. Searching for recurring patterns in protein contact maps, we found several network motifs, patterns that occur more frequently in experimentally ...

MHC motif viewer [PDF]

open access: yesImmunogenetics, 2008
In vertebrates, the major histocompatibility complex (MHC) presents peptides to the immune system. In humans, MHCs are called human leukocyte antigens (HLAs), and some of the loci encoding them are the most polymorphic in the human genome. Different MHC molecules present different subsets of peptides, and knowledge of their binding specificities is ...

AAA+ protein unfoldases—the Moirai of the proteome

open access: yesFEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Developmental motifs reveal complex structure in cell lineages

open access: yes, 2010
Many natural and technological systems are complex, with organisational structures that exhibit characteristic patterns, but defy concise description. One effective approach to analysing such systems is in terms of repeated topological motifs.
