NeoI represents a group of transcriptional repressors regulating the biosynthesis of multiple aminoglycosides

引用

Science China life Sciences 2024年

作者： yue li Xiangxi Meng Dong li Xiulei Xia Jihui Zhang Yihua Chen Huarong Tan State Key Laboratory of Microbial Resources Institute of Microbiology Chinese Academy of Sciences University of Chinese Academy of Sciences

In general, the initiation or closure of antibiotic biosynthesis is determined by regulatory proteins, but most of their mechanisms of action remain unknown. The 2-deoxystreptamine-containing aminoglycosides（2-DOS AGs） form a unique category among antibiotics. Genomic analysis revealed that a group of hypothetical regulatory genes represented by neoI are widely distributed in the biosynthetic gene clusters（BGCs） of natural products from Streptomyces species, including several 2-DOS AGs. Only limited knowledge is available for the roles of NeoItype regulators although neomycin and some of the related AGs have been developed as therapeutic drugs for decades. This study focuses on the functional determination of neoI and its homologues situated in the BGCs of six AGs. We found that the yield of neomycin in neoI disruption mutant（ΔneoI） increased by 50% compared to the wild-type（WT） strain(（420.6±44.1） mg L-1), while it was partially restored by the complementation of neoI, demonstrating that NeoI acted as a repressor in neomycin biosynthesis. Further electrophoretic mobility shift assays（EMSAs） and DNase I footprinting assays indicated that NeoI could specifically bind to the promoter region between neoE and neoI with conserved nucleotides（5'-CVHYMRCHDKAGYGGACR-3'）, as determined by site-directed mutagenesis. Interestingly, cross-bindings of the NeoI homologues from the six different BGCs to their corresponding DNA targets were manifested, and the five exogenous NeoI homologues could complement NeoI function of repressing neomycin biosynthesis. Our results suggested that NeoI-type regulators represent widespread and conservative regulatory characteristics in the biosynthesis of 2-DOS AGs, which would be significant for optimizing the biosynthetic pathways of valuable commercialized aminoglycoside antibiotics.

V0405 Dra:A New Deep and Low Mass Ratio Contact Binary with Extremely Fast Decrease in the Orbital Period

V0405 Dra is a W UMa-type binary *** on the TESS data,we have conducted an orbital period study and performed a light curve analysis for the *** orbital period study reveals that the O-C curve for V0405 Dra exhibits secular decrease at an extremely high rate of d P/dt=-2.71×10^(-6)day year^(-1),along with periodic variations characterized by an amplitude of A_(3)=0.0032 day and a period of P_(3)=1.413 *** orbital periodic change is possibly due to the light-travel time effect resulting from an additional third body in the system,for which we estimate a minimum mass of M_(3)=0.77M_(⊙).By employing the 2013 version of the Wilson-Devinney(W-D)method to synthesize a light curve,we derived photometric solutions indicating that V0405 Dra is a new deep(f=68.7%)and low-mass ratio(q=0.175)contact *** fast decrease in its orbital period is likely caused by mass transfer from the more massive primary star to the less massive secondary star,or due to angular momentum *** further mass transfer and loss of angular momentum,the binary will gradually evolve into a tighter contact configuration,eventually leading to a merger into a single star,following the evolutionary paths suggested for such deep and low mass ratio contact binaries.
