The Role of Structural Order in the Mechanism of Charge Transport across Tunnel Junctions with Various Iron‐Storing Proteins

Small, Volume 18, Issue 42, October 20, 2022., 2022
Large proteins support remarkably high charge transport rates, but the factors that influence the charge transport mechanism are still unclear. This work shows the importance of structural order: ordered structures support coherent tunnelling pathways while charges “hop” across disordered structures.

Identification of acetylated diether lipids in halophilic Archaea

MicrobiologyOpen, Volume 11, Issue 3, June 2022., 2022
Archaea‐type ether lipids have been found recently in Bacillales. They are monoether lipids with a C35 isoprenoid chain and are diacetylated by the O‐acetyltransferase YvoF. Phylogenetic studies implied that YvoF homologs also occur in Halobacteria (Archaea).

Diversity and origin of carotenoid biosynthesis: its history of coevolution towards plant photosynthesis

New Phytologist, Volume 232, Issue 2, Page 479-493, October 2021., 2021
Summary The development of photosynthesis was a highlight in the progression of bacteria. In addition to the photosystems with their structural proteins, the photosynthesis apparatus consists of different cofactors including essential carotenoids.

Bacterial‐like nitric oxide synthase in the haloalkaliphilic archaeon Natronomonas pharaonis

MicrobiologyOpen, Volume 9, Issue 11, November 2020., 2020
This study details the first characterization of an Archaeal NOS enzyme, whereby bioinformatic and biochemical approaches confirm that Natronomonas pharaonis ORF NP_1908A encodes a bacterial NOS‐like protein which can catalyze NO production in vitro. This study is also the first to describe genetic manipulation of Nmn.
