BB0259 Encompasses a Peptidoglycan Lytic Enzyme Function for Proper Assembly of Periplasmic Flagella in Borrelia burgdorferi

Autor: Hui Xu, Bo Hu, David A. Flesher, Jun Liu, Md A. Motaleb

Publikováno v: Frontiers in Microbiology, Vol 12 (2021)

Assembly of the bacterial flagellar rod, hook, and filament requires penetration through the peptidoglycan (PG) sacculus and outer membrane. In most β- and γ-proteobacteria, the protein FlgJ has two functional domains that enable PG hydrolyzing act

To compete in certain low-light environments, some cyanobacteria express a paralog of the light-harvesting phycobiliprotein, allophycocyanin (AP), that strongly absorbs far-red light (FRL). Using cryo–electron microscopy and time-resolved absorptio

Structure of a dimeric photosystem II complex from a cyanobacterium acclimated to far-red light

Autor: Christopher J. Gisriel, Gaozhong Shen, David A. Flesher, Vasily Kurashov, John H. Golbeck, Gary W. Brudvig, Muhamed Amin, Donald A. Bryant

Photosystem II (PSII) is the water-splitting enzyme central to oxygenic photosynthesis. To drive water oxidation, the energy from light is harvested by accessory pigments, mostly chlorophyll (Chl) a molecules, which absorb visible light (400-700 nm).

Significance Photosystem II (PSII) is a photo-oxidoreductase that harnesses light energy to use water to make fuel. Water oxidation occurs at a metal cluster in the active site called the oxygen-evolving complex (OEC). Understanding PSII function has

How to correct relative voxel scale factors for calculations of vector-difference Fourier maps in cryo-EM

Autor: Jimin Wang, Jinchan Liu, Christopher J. Gisriel, Shenping Wu, Federica Maschietto, David A. Flesher, Elias Lolis, George P. Lisi, Gary W. Brudvig, Yong Xiong, Victor S. Batista

Publikováno v: Journal of Structural Biology. 214:107902

The atomic coordinates derived from cryo-electron microscopy (cryo-EM) maps can be inaccurate when the voxel scaling factors are not properly calibrated. Here, we describe a method for correcting relative voxel scaling factors between pairs of cryo-E

Publikováno v: Photosynth Res

The oxygen-evolving complex (OEC) of photosystem II (PSII) cycles through redox intermediate states S(i) (i = 0–4) during the photochemical oxidation of water. The S(2) state involves an equilibrium of two isomers including the low-spin S(2) (LS-S(
