Lack of Z-DNA Conformation in Mitomycin-Modified Polynucleotides Having Inverted Circular Dichroism [PDF]

open access: yes, 1983
Poly(dG-dC)· poly(dG-dC) and Micrococcus lysodeikticus DNA were modified by exposure to reductively activated mitomycin C, an antitumor antibiotic. The resulting covalent drug-polynucleotide complexes displayed varying degrees of CD inversions, which are

Membrane selectivity and pore formation of SprA1 and SprA2 hemolytic peptides from Staphylococcus aureus type I toxin–antitoxin systems

open access: yesThe FEBS Journal, EarlyView.
When overexpressed in Staphylococcus aureus, the type I toxins SprA1 and SprA2 form membrane pores, with SprA1 creating stable pores and SprA2 forming transient ones. Both induce concomitant membrane depolarization, ATP release, and growth arrest, while only SprA1 causes membrane permeabilization due to its stable pore formation.

Dietary Phosphorus Requirement for Tambaqui, Colossoma macropomum, in the Grow‐Out Phase

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Phosphorus is essential for fish growth as it is crucial in skeletal development and metabolic reactions. The dietary requirement for this mineral varies among fish species and growth stages. Therefore, the objective of this study was to determine the available phosphorus (AP) requirement for tambaqui during the grow‐out phase (± 400 to 1000 g)

Antimicrobial peptide expression in a wild tobacco plant reveals the limits of host-microbe-manipulations in the field [PDF]

open access: yes, 2019
Plant-microbe associations are thought to be beneficial for plant growth and resistance against biotic or abiotic stresses, but for natural ecosystems, the ecological analysis of microbiome function remains in its infancy.
