TranscriptomicsProbing nucleosome function: A highly versatile library of synthetic histone H3 and H4 mutants
The structural integrity of the nucleosome is central to regulation of DNA metabolism and transcription. We describe a library of 486 systematic histone H3 and H4 substitution and deletion mutants in Saccharomyces cerevisiae that probe the contribution of each residue to nucleosome function and can ...

TranscriptomicsAccumulation of inorganic polyphosphate mediates metabolic downshift and antibiotic tolerance in Mycobacterium tuberculosis
The stringent response, involving the regulatory molecules inorganic polyphosphate (poly P) and (p)ppGpp, is believed to mediate Mycobacterium tuberculosis persistence. In this study, we identified a novel exopolyphosphatase responsible for poly P hydrolysis. Using two different poly P-accumulating ...

TranscriptomicsA genome-wide genetic interaction screen reveals metabolic roles of human histone deacetylase 1
Dynamic acetylation of metabolic proteins has emerged as a ubiquitous post-translational modification of human metabolic proteins. However, the corresponding modifying enzymes and the functions of the modification await exploration. Using a genome-wide synthetic lethality screen, we constructed a ge...

ProteomicsThe de novo design and synthesis of yeast chromosome XIII facilitates investigations on aging
In the era of synthetic biology, design, construction, and utilization of synthetic chromosomes with unique features provide a new strategy to study complex cellular processes such as aging. Herein, we successfully constructed the 884 Kb synXIII of Saccharomyces cerevisiae to investigate replicative...

MetabolomicsDeep functional analysis of synII, a 770 kb synthetic yeast chromosome
Here we report the design, construction and characterization of a 770 Kb synthetic yeast chromosome II (synII). With the UPLC-MS method, we demonstrated synII maintains a nearly wild-type phenotype and fitness despite hundreds of designer editing to it. Our phenomics, transcriptomics, proteomics dat...
