DNA double-strand breaks enhance homologous recombination in cells and have been exploited for targeted genome editing through use of engineered endonucleases. Here we report the creation and initial characterization of a group of rare-cutting, site-specific DNA nucleases produced by fusion of the restriction enzyme FokI endonuclease domain (FN) with the(More)
Recent studies indicate that the DNA recognition domain of transcription activator-like (TAL) effectors can be combined with the nuclease domain of FokI restriction enzyme to produce TAL effector nucleases (TALENs) that, in pairs, bind adjacent DNA target sites and produce double-strand breaks between the target sequences, stimulating non-homologous(More)
Survivability is a critical concern in modern telecom mesh networks because the failure of a network element may cause tremendous data and revenue loss in such networks using high-capacity optical fibers employing wavelength-division multiplexing (WDM). Multipath provisioning is a key feature of next-generation SONET/SDH networks (which can be used on top(More)
There is a constant need for new and improved drugs to combat infectious diseases, cancer, and other major life-threatening conditions. The recent development of genomics-guided approaches for novel natural product discovery has stimulated renewed interest in the search for natural product-based drugs. Genome sequence analysis of Streptomyces ambofaciens(More)
The rice (Oryza sativa) gene xa13 is a recessive resistance allele of Os-8N3, a member of the NODULIN3 (N3) gene family, located on rice chromosome 8. Os-8N3 is a susceptibility (S) gene for Xanthomonas oryzae pv oryzae, the causal agent of bacterial blight, and the recessive allele is defeated by strains of the pathogen producing any one of the type III(More)
Holomycin and its derivatives belong to a class of broad-spectrum antibacterial natural products containing a rare dithiolopyrrolone heterobicyclic scaffold. The antibacterial mechanism of dithiolopyrrolone compounds has been attributed to the inhibition of bacterial RNA polymerase activities, although the exact mode of action has not been established in(More)
For current service-oriented applications, individual web service usually cannot meet the requirements arising from real world applications, so it is necessary to combine the functionalities of different web services to obtain a composite service in response to users’ service requests. In order to address the problem of web service composition, this paper(More)
NaChBac is a bacterial voltage-gated sodium (Nav) channel that shows sequence similarity to voltage-gated calcium channels. To understand the ion-permeation mechanism of Nav channels, we combined molecular dynamics simulation, structural biology and electrophysiological approaches to investigate the recently determined structure of NavRh, a marine bacterial(More)
Bacterial blight of rice is caused by the γ-proteobacterium Xanthomonas oryzae pv. oryzae, which utilizes a group of type III TAL (transcription activator-like) effectors to induce host gene expression and condition host susceptibility. Five SWEET genes are functionally redundant to support bacterial disease, but only two were experimentally proven targets(More)
