Semi-automatic Reddy Tube

Table-top semi-automatic Reddy Tube is the product of Sacred Heart Instrumentation Centre, Sacred Heart College. This shock tube is capable of producing shock waves of Mach number ranging from 1 to 4.5. It has three sections as that of driver, driven and diaphragm sections. An air compressor is used to supply driver gas into the driven section. The driver and driven sections consist of long seamless stainless steel tubes of 48 cm and 180 cm, respectively and both have an inner diameter of 1.5 cm. While the atmospheric air is compressed into the driver section, at the critical pressure, the diaphragm is ruptured and the shock wave is generated and moves along the driven section. The sample holder is placed at 1 cm away from the open end of the driven section. The shock tube is capable to produce up to 500 shocks per hour as well as we can vary the Mach number by suitable diaphragms. More than 20 institutions including research laboratories from abroad used this shock tube and made more than 75 research publications in reputed international journals.

Structural Biochemistry Lab

Recent progress in X-ray crystallography and in particular cryo-EM (cryo-electron microscopy) has greatly advanced our understanding of the structure and dynamics of biomolecules. Although structures of several proteins have been solved in different conformational states, the dynamics and the functional mechanism of how these macromolecules operate cannot be understood from static snapshots obtained experimentally. Molecular dynamics (MD) simulations can be used to understand the dynamic nature of biomolecular systems with high spatial and temporal resolution. The lab utilizes both coarse-grained models and all-atom MD simulations to understand conformational dynamics in proteins and protein folding.
Our research interest includes understanding the conformational changes and dynamics of periplasmic binding proteins. We also probe for structural features that guide the mechanism of ligand binding in these proteins. The lab also studies ligand transport mechanism in membrane proteins, particularly glucose transporters and ATP-binding cassette (ABC) transporters. The lab also focuses on understanding protein folding and domain-swapping. Our attention here is focused on probing the folding mechanism of proteins, particularly those that domain-swap and relate this to understand the crucial mechanism that triggers folding as a domain-swapped dimer as against a monomer.
Lab facility
The lab is well equipped with 6 GPU and 6 high-end workstations, network access storage, printer, separate internet connection. The lab has close collaborations with NCBS (Bengaluru) and IIT-Madras.
