Cation‐π Interactions between Methylated Ammonium Groups and Tryptophan in the CHARMM36 Additive Force Field
Khan, Hanif Muhammad; MacKerell, Alexander D.; Reuter, Nathalie (Peer reviewed; Journal article, 2019)Cation-π interactions between tryptophan and choline or trimethylated lysines are vital for many biological processes. The performance of the additive CHARMM36 force field against target quantum mechanical data is shown ... -
Interfacial Aromatics Mediating Cation-π Interactions with Choline-Containing Lipids Can Contribute as Much to Peripheral Protein Affinity for Membranes as Aromatics Inserted below the Phosphates
Waheed, Qaiser; Khan, Hanif Muhammad; He, Tao; Roberts, Mary F.; Gershenson, Anne; Reuter, Nathalie (Peer reviewed; Journal article, 2019)Membrane-binding interfaces of peripheral proteins are restricted to a small part of their exposed surface, so the ability to engage in strong selective interactions with membrane lipids at various depths in the interface, ... -
A Role for Weak Electrostatic Interactions in Peripheral Membrane Protein Binding
Khan, Hanif Muhammad; He, Tao; Fuglebakk, Edvin; Grauffel, Cédric; Yang, Boqian; Roberts, Mary F.; Gershenson, Anne; Reuter, Nathalie (Peer reviewed; Journal article, 2016-03)Bacillus thuringiensis phosphatidylinositol-specific phospholipase C (BtPI-PLC) is a secreted virulence factor that binds specifically to phosphatidylcholine (PC) bilayers containing negatively charged phospholipids. ... -
Role of noncovalent interactions in protein peripheral membrane binding. Computational perspectives
Khan, Hanif Muhammad (Doctoral thesis, 2016-02-19)Noncovalent forces are important driving forces in nature particularly in biology, and they dictate many biological processes including the binding of peripheral protein to the cell membrane. The widely acknowledged models ... -
Specificity of Loxosceles α clade phospholipase D enzymes for choline-containing lipids: Role of a conserved aromatic cage
Moutoussamy, Emmanuel Edouard; Waheed, Qaiser; Binford, Greta J.; Khan, Hanif Muhammad; Moran, Shane M.; Eitel, Anna R.; Cordes, Matthew H.J.; Reuter, Nathalie (Journal article; Peer reviewed, 2022)Spider venom GDPD-like phospholipases D (SicTox) have been identified to be one of the major toxins in recluse spider venom. They are divided into two major clades: the α clade and the β clade. Most α clade toxins present ... -
Two homologous neutrophil serine proteases bind to POPC vesicles with different affinities: When aromatic amino acids matter
Schillinger, Anne-Sophie; Grauffel, Cédric; Khan, Hanif Muhammad; Halskau, Øyvind; Reuter, Nathalie (Peer reviewed; Journal article, 2014-12)Neutrophil serine proteases Proteinase 3 (PR3) and human neutrophil elastase (HNE) are homologous antibiotic serine proteases of the polymorphonuclear neutrophils. Despite sharing a 56% sequence identity they have been ...
