Exploration of CP12 conformational changes and of quaternary structural properties using electrospray ionization traveling wave ion mobility mass spectrometry.
Rapid Commun. Mass Spectrom. 27(1) , 179-86, (2013) CP12 is a small chloroplast protein involved in the Benson-Calvin cycle. Since it was demonstrated that the CP12 protein shared different conformational properties between reduced and oxidized states we took advantage of the segregational properties of the Tr... |

Acidic residues in the membrane-proximal stalk region of vaccinia virus protein B5 are required for glycosaminoglycan-mediated disruption of the extracellular enveloped virus outer membrane.
J. Gen. Virol. 90(Pt 7) , 1582-91, (2009) The extracellular enveloped virus (EEV) form of vaccinia virus (VACV) is surrounded by two lipid envelopes. This presents a topological problem for virus entry into cells, because a classical fusion event would only release a virion surrounded by a single env... |

Semiquinone and cluster N6 signals in His-tagged proton-translocating NADH:ubiquinone oxidoreductase (complex I) from Escherichia coli.
J. Biol. Chem. 288(20) , 14310-9, (2013) NADH:ubiquinone oxidoreductase (complex I) pumps protons across the membrane using downhill redox energy. The Escherichia coli complex I consists of 13 different subunits named NuoA-N coded by the nuo operon. Due to the low abundance of the protein and some d... |

Crystallization and preliminary X-ray crystallographic studies of cPOP1.
Acta Crystallogr. Sect. F Struct. Biol. Cryst. Commun. 69(Pt 3) , 292-4, (2013) Cellular pyrin domain-only protein 1 (cPOP1) is a pyrin domain (PYD)-containing protein that can regulate inflammation by preventing the assembly of inflammasome via direct interaction with ASC (apoptosis-associated speck-like protein containing a caspase rec... |

Non-amyloidogenic peptide tags for the regulatable self-assembling of protein-only nanoparticles.
Biomaterials 33(33) , 8714-22, (2012) Controlling the self-assembling of building blocks as nanoscale entities is a requisite for the generation of bio-inspired vehicles for nanomedicines. A wide spectrum of functional peptides has been incorporated to different types of nanoparticles for the del... |

Site-specific PEGylation at histidine tags.
Bioconjug. Chem. 23(2) , 248-63, (2012) The efficacy of protein-based medicines can be compromised by their rapid clearance from the blood circulatory system. Achieving optimal pharmacokinetics is a key requirement for the successful development of safe protein-based medicines. Protein PEGylation i... |

Optimizing protein coordination to quantum dots with designer peptidyl linkers.
Bioconjug. Chem. 24(2) , 269-81, (2013) Semiconductor quantum dots (QDs) demonstrate select optical properties that make them of particular use in biological imaging and biosensing. Controlled attachment of biomolecules such as proteins to the QD surface is thus critically necessary for development... |

Effects of pH-sensitive chain length on release of doxorubicin from mPEG-b-PH-b-PLLA nanoparticles.
Int. J. Nanomedicine 7 , 4433-46, (2012) Two methoxyl poly(ethylene glycol)-poly(L-histidine)-poly(L-lactide) (mPEG-PH-PLLA) triblock copolymers with different poly(L-histidine) chain lengths were synthesized. The morphology and biocompatibility of these self-assembled nanoparticles was investigated... |

Poly(L-histidine)-tagged 5-aminolevulinic acid prodrugs: new photosensitizing precursors of protoporphyrin IX for photodynamic colon cancer therapy.
Int. J. Nanomedicine 7 , 2497-512, (2012) 5-Aminolevulinic acid (ALA) and its derivatives have been widely used in photodynamic therapy. The main drawback associated with ALA-based photodynamic therapy (ALA-PDT) and ALA fluorescence diagnosis results from the hydrophilic nature of ALA and lack of sel... |
