Excited to announce our new paper in Nature Microbiology describing diphtheria toxin homologues in Streptomyces called Streptomyces antiquus insecticidal proteins (SAIP), stemming from a long term collaboration with Ying Xu, Min Dong, Cameron Currie, and many others. www.nature.com/articles/s41...

Has anyone had recent contact with NCBI regarding genome submissions? I've got some that I want released for an accepted paper, but have had zero luck getting a response to requests for immediate release.

We then show that SAIPs are insecticidal and used CRISPR-Cas9 screening to determine that their receptor is an insect membrane protein called Flower. This protein is localized to neurons, and we find that SAIP binding leads to insect paralysis, immunosuppression, and death.

Finally, we show that these toxigenic Streptomyces produce secondary metabolites when they consume insect carcassess. This work is the first demonstration of an exotoxin in Streptomyces and suggests they could be cryptic insect pathogens. If you're interested, please check out our paper!

We determined that these toxins evolved more than 100 million years ago in a lineage of Streptomyces and have been maintained through vertical transmission under strong stabilizing selection.

We then demonstrate that SAIPs possess a conserved structure and identical mechanism of action as diphtheria toxin (DT). However, the receptor binding domain does not resemble the corresponding domain in DT.

We have been dealing with high background using erythromycin selection for multiple E. coli strains in my lab. We've tried multiple vendors and lots, but the problem persists. Has anyone else had this problem before? Any ideas?

Some of my first year grad students in my class are asking for books to read that will get them thinking about what questions to ask and how to know what they should ask. I have a couple of recs but wondering if anyone can help. What inspired you??

Somewhere in the U.S., there’s a scientist staring at their NSF/NIH grant application wondering why they bother. This post is for you. Science and society both need you. Hang in there and know there is a whole community supporting you.

Are you working on natural products? We’ve just released version 4.0 of the MIBiG data standard and repository! It now includes 3059 biosynthetic gene clusters, thanks to the combined efforts of 288 expert contributors. A thread: (1/8) academic.oup.com/nar/advance-...

Working on an analysis using published data in the SRA, but missing metadata is an issue. About half of the authors I've contacted shared it upon request, the rest haven’t responded despite follow-ups. Debating whether to keep asking, contact journals, or move on. Any advice?
