Optimized Fertilization Balances Microbial Carbon and Nitrogen Use Efficiency: Evidence From Microbial Communities

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Optimized fertilization involving reduced mineral N input and organic substitution can alter resource stoichiometry, microbial carbon use efficiency (CUE) and nitrogen use efficiency (NUE). However, how fertilization‐induced resource imbalance reshapes microbial community to regulate CUE and NUE remains unclear. We conducted a field experiment

Biochar‐Induced Shifts in Resource Stoichiometry Shape Potential Nitrogen Limitation and Estimated Microbial Carbon Use Efficiency in Tropical Soils

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Biochar is widely recognized as a promising amendment for enhancing soil carbon sequestration and microbial functioning, yet how biochar properties and application levels jointly influence potential microbial nutrient limitation and estimated microbial carbon use efficiency (CUE) remains unclear, especially in tropical farmland soils.

Mechanisms of HIV Protein Degradation into Epitopes: Implications for Vaccine Design

open access: yesViruses, 2014
The degradation of HIV-derived proteins into epitopes displayed by MHC-I or MHC-II are the first events leading to the priming of HIV-specific immune responses and to the recognition of infected cells.

Effect of Stand Density on Soil Microbial Carbon and Nitrogen Use Efficiency in Robinia pseudoacacia Plantations in the Loess Hilly‐Gully Region, China

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Soil microbial carbon (CUE) and nitrogen (NUE) use efficiency are critical for soil carbon (C) sequestration and nitrogen (N) availability. However, how microbial CUE and NUE respond to stand density is unclear. Furthermore, it remains unclear whether the response of microbial CUE and NUE to stand density could be mediated by soil depth.

Type II Secretion-Dependent Aminopeptidase LapA and Acyltransferase PlaC Are Redundant for Nutrient Acquisition during Legionella pneumophila Intracellular Infection of Amoebas

open access: yesmBio, 2018
Legionella pneumophila genes encoding LapA, LapB, and PlaC were identified as the most highly upregulated type II secretion (T2S) genes during infection of Acanthamoeba castellanii, although these genes had been considered dispensable on the basis of the

Effects of Composite Reclamation Models of Sea Buckthorn, A Pioneer Species in Semi‐Arid Regions, on Soil Quality and Microbial Communities

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Open‐pit coal mining severely degrades soil and ecosystem functions, constraining regional sustainability. Vegetation‐based reclamation has therefore been widely adopted as an effective approach to promote soil recovery and ecosystem restoration.

Methionine aminopeptidase associated with liver mitochondria and microsomes

open access: yes, 1981
A new, unstable, particle-bound (particularly mitochondria and microsomes) aminopeptidase, mol. wt 74,000, was partially purified from rat liver. Among five aminoacyl-β-naphthylamides assayed, MetNA was the best substrate. The aminopeptidase releases NH2-

Structure-Function and Industrial Relevance of Bacterial Aminopeptidase P

open access: yes, 2021
Aminopeptidase P (APPro, E.C 3.4.11.9) cleaves N-terminal amino acids from peptides and proteins where the penultimate residue is proline. This metal-ion-dependent enzyme shares a similar fold, catalytic mechanism, and substrate specificity with ...

Storage treatment and diluent cause inconsistencies in commonly used fluorometric microplate enzyme assays conducted with saltmarsh soils

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Fluorometric enzyme assays are a tool for determining potential enzyme activity in soils. A wide array of methodological approaches is adopted by different studies, making comparisons difficult. An important consideration is whether assay conditions replicate the environment of the samples or optimize potential enzyme activity.
