Adaptability and specificity: how do proteins balance opposing needs to achieve function?

期刊: CURRENT OPINION IN STRUCTURAL BIOLOGY, 2021; 67 ()

Many proteins select from a small repertoire of 3-dimensional folds retained over evolutional timescales and recruited for different functions, with c......

Protein N-glycosylation and O-mannosylation are catalyzed by two evolutionarily related GT-C glycosyltransferases

期刊: CURRENT OPINION IN STRUCTURAL BIOLOGY, 2021; 68 ()

The structural folds of glycosyltransferases are categorized into three superfamilies: GT-A, GT-B, and GT-C. Few structures of GT-C fold existed in th......

Elucidating molecular mechanisms of functional conformational changes of proteins via Markov state models

期刊: CURRENT OPINION IN STRUCTURAL BIOLOGY, 2021; 67 ()

Functional conformational changes of proteins can facilitate numerous biological events in cells. The Markov state model (MSM) built from molecular dy......

Histone tails as signaling antennas of chromatin

期刊: CURRENT OPINION IN STRUCTURAL BIOLOGY, 2021; 67 ()

Histone tails, representing the N-terminal or C-terminal regions flanking the histone core, play essential roles in chromatin signaling networks. Intr......

Allostery of multidomain proteins with disordered linkers

期刊: CURRENT OPINION IN STRUCTURAL BIOLOGY, 2020; 62 ()

Intrinsically disordered regions are often involved in allosteric regulation of multidomain proteins. They can act as disordered linkers to connect an......

Allosteric regulation of CRISPR-Cas9 for DNA-targeting and cleavage

期刊: CURRENT OPINION IN STRUCTURAL BIOLOGY, 2020; 62 ()

The CRISPR-Cas9 system from Streptococcus pyogenes has been exploited as a programmable RNA-guided DNA-targeting and DNA-editing platform. This evolut......

Protein topology and allostery

期刊: CURRENT OPINION IN STRUCTURAL BIOLOGY, 2020; 62 ()

Allostery plays important roles in many biological processes. Although all non-fibrous proteins may be allosteric, currently only a limited number of ......

Intrinsic dynamics is evolutionarily optimized to enable allosteric behavior

期刊: CURRENT OPINION IN STRUCTURAL BIOLOGY, 2020; 62 ()

Allosteric behavior is central to the function of many proteins, enabling molecular machinery, metabolism, signaling and regulation. Recent years have......

Dynamic multivalent interactions of intrinsically disordered proteins

期刊: CURRENT OPINION IN STRUCTURAL BIOLOGY, 2020; 62 ()

Protein-protein interactions involving intrinsically disordered proteins (IDPs) usually display dynamic and multivalent features. Recent experimental ......

Chromatin structure changes during various processes from a DNA sequence view

期刊: CURRENT OPINION IN STRUCTURAL BIOLOGY, 2020; 62 ()

Chromatin mainly consists of protein and DNA, and the sequence information of DNA contributes to controlling the spatial structure of chromatin. Genom......

Structural features of activated GPCR signaling complexes

期刊: CURRENT OPINION IN STRUCTURAL BIOLOGY, 2020; 63 ()

G protein-coupled receptors (GPCRs) couple to diverse heterotrimeric G protein subtypes and then activate downstream signaling pathways in classical G......

Assembly of eukaryotic photosystem II with diverse light-harvesting antennas

期刊: CURRENT OPINION IN STRUCTURAL BIOLOGY, 2020; 63 ()

Photosystem II (PSII) catalyzes the light-driven oxygen-evolving reaction via its catalytic core and peripheral light-harvesting antennas. Oxyphototro......

High-resolution views of lipopolysaccharide translocation driven by ABC transporters MsbA and LptB(2)FGC

期刊: CURRENT OPINION IN STRUCTURAL BIOLOGY, 2020; 63 ()

Gram-negative bacteria possess a dual-membrane envelope, which provides defense against environmental assault, as well as formidable resistance agains......
