DRAM for distilling microbial metabolism to automate the curation of microbiome function

Nucleic Acids Research, Journal Year: 2020, Volume and Issue: 48(16), P. 8883 - 8900

Published: July 22, 2020

Abstract Microbial and viral communities transform the chemistry of Earth's ecosystems, yet specific reactions catalyzed by these biological engines are hard to decode due absence a scalable, metabolically resolved, annotation software. Here, we present DRAM (Distilled Refined Annotation Metabolism), framework translate deluge microbiome-based genomic information into catalog microbial traits. To demonstrate applicability across diverse genomes, evaluated performance on defined, in silico soil community previously published human gut metagenomes. We show that accurately assigned contributions geochemical cycles automated partitioning carbohydrate metabolism at substrate levels. DRAM-v, mode DRAM, established rules identify virally-encoded auxiliary metabolic genes (AMGs), resulting categorization thousands putative AMGs from soils guts. Together DRAM-v provide critical profiling capabilities decipher mechanisms underpinning microbiome function.

Nanocatalytic Medicine

Advanced Materials, Journal Year: 2019, Volume and Issue: 31(39)

Published: July 22, 2019

Abstract Catalysis and medicine are often considered as two independent research fields with their own respective scientific phenomena. Promoted by recent advances in nanochemistry, large numbers of nanocatalysts, such nanozymes, photocatalysts, electrocatalysts, have been applied vivo to initiate catalytic reactions modulate biological microenvironments for generating therapeutic effects. The rapid growth biomedical applications nanocatalysts has led the concept “nanocatalytic medicine,” which is expected promote further advance a subdiscipline nanomedicine. high efficiency selectivity catalysis that chemists strived achieve past century can be ingeniously translated into efficacy mitigated side effects theranostics using medicine” steer optimized outcomes. Here, rationale behind construction nanocatalytic eludicated based on essential reaction factors (catalysts, energy input, reactant). Recent this burgeoning field then comprehensively presented mechanisms nanosystems conferred theranostic functions discussed detail. It believed an emerging modality will play more important role

Trophic Interactions and the Drivers of Microbial Community Assembly

Current Biology, Journal Year: 2020, Volume and Issue: 30(19), P. R1176 - R1188

Published: Oct. 1, 2020

Despite numerous surveys of gene and species content in heterotrophic microbial communities, such as those found animal guts, oceans, or soils, it is still unclear whether there are generalizable biological ecological processes that control their dynamics function. Here, we review experimental theoretical advances to argue networks trophic interactions, which the metabolic excretions one primary resource for another, constitute central drivers community assembly. Trophic interactions emerge from deconstruction complex forms organic matter into a wealth smaller intermediates, some released environment serve nutritional buffet community. The structure emergent network rate at resources supplied many features assembly, including relative contributions competition cooperation emergence alternative states. Viewing assembly through lens also has important implications spatial communities well functional redundancy taxonomic groups. Given ubiquity across environments, they impart common logic can enable development more quantitative predictive ecology.

Microbes in Guaymas Basin (Gulf of California) hydrothermal sediments thrive on hydrocarbons and sulfur experience steep, fluctuating temperature chemical gradients. The functional capacities communities inhabiting this dynamic habitat are largely unknown. Here, we reconstructed 551 genomes from hydrothermally influenced, nearby cold belonging to 56 phyla (40 uncultured). These comprise 22 unique lineages, including five new candidate phyla. In contrast findings hydrocarbon seeps, hydrothermal-associated more diverse archaea dominate over bacteria. Genome-based metabolic inferences provide first insights into the ecological niches these uncultured microbes, methane cycling Crenarchaeota alkane utilization ANME-1. shaped by a high biodiversity, partitioning among nitrogen pathways redundancy core carbon-processing pathways. select for distinctive microbial that stand out expansive open up physiological perspectives ecosystem function.
