Role of non-active site residue Trp-93 in the function and stability of New Delhi Metallo-β-Lactamase-1 (NDM-1).

Rehman MT1, Khan AU2.
Antimicrobial agents and chemotherapy.Antimicrob Agents Chemother.2015 Nov 2. pii: AAC.01194-15. [Epub ahead of print]
New Delhi metallo-β-lactamase-1 (NDM-1) is expressed by various members of Enterobacteriaceae as a defence mechanism to hydrolyze β-lactam antibiotics. Despite various studies showing the significance of active site residues in the catalytic mechanism, there is paucity of reports addressing the ro

Structure of protonated thymidine characterized by infrared multiple photon dissociation and quantum calculations.

Salpin JY1,2, Scuderi D3,4.
Rapid communications in mass spectrometry : RCM.Rapid Commun Mass Spectrom.2015 Oct 30;29(20):1898-904. doi: 10.1002/rcm.7296.
RATIONALE: Many fundamental studies are motivated by the probable relationship between the presence of rare enol tautomers of nucleobases and point mutation developing during nucleic acid replication. The evaluation of the tautomeric behaviour of nucleobases is therefore of fundamental importance. T

Because of the success of imatinib, the first type-II kinase inhibitor approved by the FDA in 2001, sustained efforts have been made by the pharmaceutical industry to discover novel compounds stabilizing the inactive conformation of protein kinases. On the seven type-II inhibitors having reached the

Polycationic Gramicidin S Analogues with Both High Antibiotic Activity and Very Low Hemolytic Activity

Tamaki Makoto,Harada Takuji,Fujinuma Kenta [他],Takanashi Kazumasa,Shindo Mitsuno,Kimura Masahiro,Uchida Yoshiki
Chemical and Pharmaceutical Bulletin 60(9), 1134-1138, 2012
… The substitution of each constituent amino acid residue of gramicidin S (GS), cyclo(-Val1,1′-Orn2,2′-Leu3,3′-D-Phe4,4′-Pro5,5′-)2 with Lys residue indicated that each side chain structure of the constituent amino acid residues affect largely the antibiotic activity and hemolytic activity of GS. …

Steric hindrance by 2 amino acid residues determines the substrate specificity of isomaltase from Saccharomyces cerevisiae(ENZYMOLOGY, PROTEIN ENGINEERING, AND ENZYME TECHNOLOGY)

Journal of bioscience and bioengineering 112(6), 545-550, 2011-12
… The superposition of maltose onto the E277A-maltose structure revealed that the reducing end of maltose cannot bind to the subsite+1 due to the steric hindrance from Val216 and Gln279. … The amino acid sequence comparisons with α-glucosidases showed that a bulky hydrophobic amino acid residue is conserved at the position of Val216 in α-1,6-glucosidic linkage hydrolyzing enzymes. …
