1st Advancing Mass Spectrometry for Biophysics and Structural Biology Conference Launches at UM

AMS Conference photograph, 116 scientists from 9 different countries were represented at the kick-off meeting at UM July 28th- Aug 1st.

From July 28th to August 1st,  The University of Michigan Department of Chemistry played host to a new scientific conference that seeks to bridge the growing needs of the biopharmaceutical industry with the an emerging area of academic research focused on an area of research known as ‘gas-phase structural biology’.

The new conference is called Advancing Mass Spectrometry for Biophysics and Structural Biology (or AMS for short), and featured 47 oral presentations and 69 posters contributed from an international group of 116 scientists representing 9 different countries.

Brandon Ruotolo, Associate Professor in the UM Chemistry Department, served as conference organizer and chair for the 2017 meeting.

The first AMS meeting covered a range of topics concerned with the development of new mass spectrometry tools capable of rapidly capturing the 3D structures and stabilities of large biomolecules present within complex mixtures at low levels.

Such technologies are of growing importance to the biopharmaceutical industry, a sector that is producing an ever increasing number of therapeutics based on large protein vehicles, an endeavor that currently represents a $60 Billion research investment in that industry.

The 2019 AMS meeting will take place in Amherst MA, at the University of Massachusetts.

Protein structure and integrative modeling with ion mobility mass spectrometry explained using legos

by Sugyan Dixit (3rd year graduate student) and Sarah Fantin (2nd year graduate student)

On Tuesday, April 4th 2017, a collaborative effort between CSIE|UM, a graduate students/postdoctoral fellows led professional development group, and the Ann Arbor Hands on Museum, a local interactive science, math, and technology museum for children, put forward several activities and demos from different research groups at UM chemistry department. This event was the last event in a four part series called “Science for the Public” promoting understanding of scientific research to the general public.

Our lab put together a fun demo titled “Lego Fragmentation” to explain the public about the structure and function of proteins/protein complexes in general as well as give an idea of how we use ion mobility mass spectrometry (IM-MS) as a platform to study protein structure. There were two parts to this demo: 1) building a helix structure using the legos and 2) solving lego puzzles to correctly put together a structure. Several kids came over to play with legos and almost everyone tried to build the helix structure. This activity was aimed at introducing structure of peptides/proteins in a very simplistic manner.

The second activity, “Lego Fragmentation”, was a bit more challenging as we put together two models of a structure with different breaking points in order for kids to analyze the pieces and put the pieces back to yield two identical models (IM-MS integrative modeling).

Level 3 model. Although they are identical, they have different breaking points yielding different pieces. The task is to analyze the pieces and put together the models as shown here.

We had three levels of difficulty, from easy to hard. Few kids attempted the puzzle. As soon as they got the idea of the puzzle from our easy assembly, they were excited to try the harder levels. Interestingly, the parents participated in solving the puzzle as well.

While kids and parents worked together to build the lego model from its pieces, we got the opportunity to communicate the role of IM-MS integrative modeling in determining protein complexes’ structure and explain the importance of studying protein’s structure and function with the implication on understanding diseases and pathway for finding cure to diseases.
