Brian Geiss Gets Number 9,206,412
Brian Geiss, along with two co-workers, recently received US patent 9,206,412 for their discovery of the antiviral activity of a new class of inhibitors that bind to and inhibit flavivirus NS5 guanylyltransferase function. This was the first class of antiviral inhibitors identified that specifically interfere with the formation of the viral RNA cap structure.
Infectious Disease Research and Response Network (IDR2N) Designated as a CSU Program of Research and Scholarly Excellence
We are pleased to announce that the IDR2N is one of 21 newly designated Programs in Research and Scholarly Excellence (PRSE) by the Office of the Vice President for Research. The IDR2N consists of 62 faculty from seven departments, the lion’s share of which reside in MIP. The goals of the IDR2N are to build upon the extensive infectious disease research foundation already in place at CSU and (1) enhance the response of CSU infectious disease research community to opportunities, (2) establish effective clinical collaborations, (3) promote state-of-the-art research and research infrastructure, and (4) expand infectious disease research training opportunities. Congratulations to John Belisle who spearheaded the effort to create the IDR2N and we look forward to exciting times ahead!

From Donald Trump to Mycobacteria, seems like everyone these days wants to build a wall. The trick of course, is how to do it effectively (and of course who will pay for it). While we don’t have any answers for Mr. Trump’s wall, this paper by Anna et al provides a pretty interesting clue to how mycobacteria effectively wall themselves off from their neighbors.
Building a mycobacterial cell wall requires several key steps – and one of the most important ones is covalently linking the fundamental peptidoglycan (PG) component to the arabinogalactan (AG) moieties that allow the external wall components to be effectively assembled. However the enzyme that’s responsible for this important ‘PG-AG’ linkage has been a puzzling question for many years. Our MRL team, along with their international collaborators, came up with an interesting hypothesis to address this knowledge gap. Other Gram positive bacteria use enzymes from the LCP family of proteins to attach things to their peptidoglycans – and Mycobacteria possess three LCP family homologs. Not only that, but knocking out a LCP protein in Corynebacteria leads to clear cell wall assembly defects. Could one or more of these three mycobacteria LCP homologs be the culprits that attach AG to PG?
The team stopped hypothesizing and started experimenting, using a series of biochemical and genetic assays to find out. Three pieces of evidence convinced them that the Mycobacteria ‘CpsA1 and A2’ genes are key architects of the mycobacteria membrane core. First, the CpsA1 and A2 proteins are found precisely on the membrane where they would need to be to attach AG to PG. Second, recombinantly produced CpsA1 and A2 proteins act as Mg-dependent pyrophosphatases, which is precisely the enzymatic activity they would need to mediate PG-AG attachment. Finally, while knocking out both proteins is lethal, knocking out CpsA1 causes growth defects as well as membrane cording defects in certain mycobacaterial genetic backgrounds. Therefore despite the lack of a definitive assay to easily assess LCP protein function in mycobacteria, these three lines of evidence provide a strong indication that CpsA1 and CpsA2 are very likely the enzymes involved in AG attachment to PG.
So why did we choose this study as our MIPublication of the Month© for July? First, given that many of our most effective antibiotics target bacterial cell wall synthesis, the identification of CpsA1/A2 as key cell wall enzymes in Mycobacteria tuberculosis is obviously a big deal. In fact, inactivating the CpsA1 protein in Mtb makes it much more susceptible to a variety of known antibiotics – perhaps due to a flimsy, hypersensitive cell wall that is constructed in the absence of the LCP protein. Second, this paper is authored by not only three faculty/ laboratories in the CSU-MRL, but also has collaborators from five other countries on two other continents. The study is thus a poster child of synergy and international cooperation – in fact there are co-first authors (Anna and Celia) as well as co-senior authors (Mary and Christine). Finally, with the Rio Olympics track and field events to begin shortly, we wanted to make sure we picked a paper that was fast – and this paper is ‘acid’ fast…….

One Health: Vet Resident Does UCHSC Lab Rotation
Anna Fagre spent three weeks at CU Health shadowing physicians and technicians in the Clinical Microbiology Lab. She attended rounds with all of the residents and internists three times a week and went through a self-guided set of unknowns. This was a great way to extend one’s diagnostic training by learning how a high-throughput human microbiology lab is run.
