Photoclickable dendritic molecular glue: noncovalent-to-covalent photochemical transformation of protein hybrids.
J. Am. Chem. Soc. 135(12) , 4684-7, (2013) A water-soluble dendron with a fluorescein isothiocyanate (FITC) fluorescent label and bearing nine pendant guanidinium ion (Gu(+))/benzophenone (BP) pairs at its periphery (Glue(BP)-FITC) serves as a "photoclickable molecular glue". By multivalent salt-bridg... |

Kinetic evidence for a two-stage mechanism of protein denaturation by guanidinium chloride.
Proc. Natl. Acad. Sci. U. S. A. 111(13) , 4856-61, (2014) Dry molten globular (DMG) intermediates, an expanded form of the native protein with a dry core, have been observed during denaturant-induced unfolding of many proteins. These observations are counterintuitive because traditional models of chemical denaturati... |

Thermodynamic effects of the alteration of the axial ligand on the unfolding of thermostable cytochrome C.
Biochemistry 52(8) , 1373-84, (2013) The role the axial methionine plays in the conformational properties and thermostability of the heme active site has been investigated with the help of site-specific mutations at the axial Met69 position with His (M69H) and Ala (M69A) in thermostable cytochro... |

Stabilization of ferrochelatase via lysine residues on the carboxyl terminal extension.
Protein Pept. Lett. 20(9) , 977-81, (2013) There are accumulating evidences suggesting that ferrochelatase is involved in different cellular functions other than heme biosynthesis. The carboxyl-terminal extension of the enzyme may play a role associated with its stability and signaling process. Two tr... |

Pre-existent asymmetry in the human cyclooxygenase-2 sequence homodimer.
J. Biol. Chem. 288(40) , 28641-55, (2013) Prostaglandin endoperoxide H synthase-2 (PGHS-2), also known as cyclooxygenase-2 (COX-2), is a sequence homodimer. However, the enzyme exhibits half-site heme and inhibitor binding and functions as a conformational heterodimer having a catalytic subunit (Ecat... |

A template approach for the characterization of linear polyamines and derivatives in spider venom.
Eur. J. Mass Spectrom. (Chichester, Eng.) 19(1) , 57-69, (2013) A combination of high-performance liquid chromatography (HPLC) and atmospheric-pressure chemical ionization mass spectrometry (APCI-MS and APCI-MS/MS) was used to detect and characterize linear polyamine derivatives in the venom of the spiders Agelenopsis ape... |
