GlmY and GlmZ: a hierarchically acting cascade composed of two small RNAs
(2014-09-10)In Escherichia coli and other enterobacteria, the homologous small RNAs (sRNAs) GlmY and GlmZ act in a hierarchical manner to feedback control expression of key enzyme glucosamine-6-phosphate (GlcN6P) synthase GlmS. Enzyme ... -
Identification and Characterization of Microbial Key Functions in Soils of the German Biodiversity Exploratories Representing Different Land Use and Management Types
(2012-05-11)Soil probably harbors the highest microbial species diversity of any environment on Earth and represents a major reservoir of microbial taxonomic, genomic, and metabolic diversity. The most promising approach to gain ... -
Identifikation von Genen und Mikroorganismen, die an der dissimilatorischen Fe(III)-Reduktion beteiligt sind
(2009-05-06)Dissimilatory iron reduction is one of the earliest, perhaps the first form of an anoxic respiratory system on earth. Microorganisms harboring this system couple their growth to the ... -
Identifizierung und Charakterisierung von Genen und korrespondierenden Genprodukten aus Metagenombanken, die Butanol-Dehydrogenase-Aktivität oder proteolytische Aktivität vermitteln
(2006-07-07)The cultivation-independent assessment and exploitation of the vast microbial diversity by metagenomics offers an almost unlimited resource of new genes, gene products, and biosynthetic ... -
Impact of Rain Forest Transformation on Roots and Functional Diversity of Root-Associated Fungal Communities
(2017-12-07)Tropical rain forests are representing biodiversity hotspots, but their species richness is threatened by human driven land use changes. Between 1990 and 2015 most of the global deforestation of about 129 million hectares ... -
Investigation of storage polysaccharide metabolism in lactic acid bacteria
(2011-10-21)Glycogen biosynthesis and its regulation have been investigated extensively in bacteria at the level of ADP-Glc synthesis. The enzyme ADP-glucose pyrophosphorylase (ATP: α-dglucose-1-phosphate ... -
