Purificación y caracterización de hidrolasas implicadas en el microparasitismo de Trichoderma harzianum
(1994)
Los hongos del genero Trichoderma son buenos agentes de control biológico. Entre los mecanismos que estos utilizan para combatir las enfermedades de plantas producidas por hongos se encuentra el fenómeno denominado ...

Characterization of NO-Induced Nitrosative Status in Human Placenta from Pregnant Women with Gestational Diabetes Mellitus
(Hindawi Publishing Corporation, 2017)
Dysregulation of NO production is implicated in pregnancy-related diseases, including gestational diabetes mellitus (GDM). The role of NO and its placental targets in GDM pregnancies has yet to be determined. S-Nitrosylation ...

Chromatin-dependent regulation of RNA polymerases II and III activity throughout the transcription cycle
(Oxford University Press, 2015)
The particular behaviour of eukaryotic RNA polymerases along different gene regions and amongst distinct gene functional groups is not totally understood. To cast light onto the alternative active or backtracking states ...

Reparación postreplicativa de cortes de doble cadena en Saccharomyces Cerevisiae
(2006-07-21)
Entendemos como corte de doble cadena (doublé-strand break, DSB) toda interrupción en la continuidad de una molécula de ADN que afecte simultáneamente a las dos cadenas que la componen. A pesar de que DSBs programados son ...

Escherichia coli SPFH Membrane Microdomain Proteins HflKC Contribute to Aminoglycoside and Oxidative Stress Tolerance
(American Society for Microbiology, 2023)
Many eukaryotic membrane-dependent functions are often spatially and temporally regulated by membrane microdomains (FMMs), also known as lipid rafts. These domains are enriched in polyisoprenoid lipids and scaffolding ...

Npa1p is an essential trans-acting factor required for an early step in the assembly of 60S ribosomal subunits in Saccharomyces cerevisiae
(Cold Spring Harbor Laboratory Press, 2004)
Ribosome biogenesis requires > 100 nonribosomal proteins, which are associated with different preribosomal particles. The substrates, the interacting partners, and the timing of action of most of these proteins are largely ...

Gibberellins and carotenoids in the wild type and mutants of Gibberella fujikuroi
(American Society for Microbiology, 1991)
A new screening procedure was used to isolate 14 gib mut ts of Gi!'berella_ fujikurof wit modi cations the production of gibberellins. The production of carotenmds and g bberellms was mvestlgated m the gib mutants and ...

Hpr1 is preferentially required for transcription of either long or G+C-rich DNA sequences in Saccharomyces cerevisiae
(American Society for Microbiology, 2001)
Hpr1 forms, together with Tho2, Mft1, and Thp2, the THO complex, which controls transcription elongation and genome stability in Saccharomyces cerevisiae. Mutations in genes encoding the THO complex confer strong trans ...
