Self-establishing communities enable cooperative metabolite exchange in a eukaryote [PDF]

open access: yes, 2015
Metabolite exchange among co-growing cells is frequent by nature, however, is not necessarily occurring at growth-relevant quantities indicative of non-cell-autonomous metabolic function.

DNA demethylation pathways: Additional players and regulators. [PDF]

open access: yes, 2017
DNA demethylation can occur passively by "dilution" of methylation marks by DNA replication, or actively and independently of DNA replication. Direct conversion of 5-methylcytosine (5mC) to cytosine (C), as originally proposed, does not occur.

Construction of a flocculent saccharomyces cerevisiae fermenting lactose [PDF]

open access: yes, 1999
A flocculent Saccharomyces cerevisiae strain with the ability to express both the LAC4 (coding for b-galactosidase) and LAC12 (coding for lactose permease) genes of Kluyveromyces marxianus was constructed.

Orotic Aciduria [PDF]

open access: yes, 2018
Orotic acid is an intermediate found in the pathway for pyrimidine synthesis. The mitochondrial enzyme dihydroorotate dehydrogenase (DHODH) catalyzes the production of orotic acid by the conversion of the compound dihydroorotate to orotic acid.

Integration of DNA into bacterial chromosomes from plasmids without a counter-selection marker. [PDF]

open access: yes, 2011
Most bacteria can only be transformed with circular plasmids, so robust DNA integration methods for these rely upon selection of single-crossover clones followed by counter-selection of double-crossover clones.

Centromeric Sequences in Ogataea polymorpha Genome Enable Development of Stable Multigene Expression Plasmid Tools

open access: yesMicrobial Biotechnology, Volume 18, Issue 11, November 2025.
The centromeric sequences of Ogataea polymorpha, a methylotrophic non‐conventional yeast, were characterised for the first time and support the development of new genetically stable centromeric plasmids with high genetic stability and compatibility, providing powerful genetic toolboxes for the synthetic biology and metabolic engineering‐driven ...

Identification of MscS as a Key L‐Glutamate Exporter in Bacillus methanolicus

open access: yesMicrobial Biotechnology, Volume 18, Issue 10, October 2025.
l‐Glutamate export in the methylotrophic bacterium Bacillus methanolicus, driven by an MscS‐like mechanosensitive channel. Figure created with BioRender (https://BioRender.com/t99s28). ABSTRACT Small‐conductance mechanosensitive channels (MscS) are established l‐glutamate exporters in industrially relevant bacteria, yet their role in the methylotrophic

Deletion of the Zinc Transporter Lipoprotein AdcAII Causes Hyperencapsulation of Streptococcus pneumoniae Associated with Distinct Alleles of the Type I Restriction-Modification System. [PDF]

open access: yes, 2020
The capsule is the dominant Streptococcus pneumoniae virulence factor, yet how variation in capsule thickness is regulated is poorly understood. Here, we describe an unexpected relationship between mutation of adcAII, which encodes a zinc uptake ...

Improvement of β‐Xylosidase and Endoxylanase Activities in Talaromyces amestolkiae by Genetic Manipulation of the Transcriptional Activator XlnR

open access: yesMicrobial Biotechnology, Volume 18, Issue 5, May 2025.
A successful transformation procedure for the genetic manipulation of the fungus Talaromyces amestolkiae was developed, enabling the forced expression of the transcriptional activator XlnR. A mutant version of XlnR carrying a Val785Phe substitution led to remarkably higher β‐xylosidase and endoxylanase activities compared to the wild‐type strain, which
