Mitochondria are highly dynamic organelles that undergo frequent fusion and fission. The large GTPase optic atrophy 1 (OPA1) is identified as a core component of inner membrane (IM) fusion. OPA1 exists as the membrane-anchored L-OPA1 and the proteolytically cleavage soluble S-OPA1. Recently, we showed that OPA1 and mitochondria-localized lipid cardiolipin (CL) cooperate in heterotypic IM fusion [Ban...

Branching in Amyloid Fibril Growth

Biophysical Journal > 2009 > 96 > 4 > 1529-1536

Using the peptide hormone glucagon and Aβ(1–40) as model systems, we have sought to elucidate the mechanisms by which fibrils grow and multiply. We here present real-time observations of growing fibrils at a single-fibril level. Growing from preformed seeds, glucagon fibrils were able to generate new fibril ends by continuously branching into new fibrils. To our knowledge, this is the first time amyloid...

Biotin-containing phospholipid vesicle layer formed on self-assembled monolayer of a saccharide-terminated alkyl disulfide for surface plasmon resonance biosensing

Journal of Bioscience and Bioengineering > 2008 > 105 > 5 > 527-535

We describe a technique to form a biotin-containing phospholipid vesicle layer on a self-assembled monolayer (SAM) deposited on a gold surface to immobilize biotinylated receptor proteins for a surface plasmon resonance (SPR) biosensor. The adsorption of vesicle of 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC) was examined by SPR on the SAMs of dithiobis(1-deoxy-glucitol-1-carbamoyl pentane) (DDGP),...

Structural observation of complexes of FGF-2 and regioselectively desulfated heparin in aqueous solutions

Yoshiaki Yuguchi, Rieko Kominato, Tadato Ban, Hiroshi Urakawa, more

International Journal of Biological Macromolecules > 2005 > 35 > 1-2 > 19-25

In order to clarify the mechanism of interaction between FGF-2 and heparin, the association structures between human FGF-2 and different kinds of regioselectively desulfated heparins were observed by small angle X-ray scattering. In the FGF-2-native heparin complex, the global FGF-2 molecules appeared to attach along heparin chain as strained unilaterally. The complexes with the 6-O-, or N-desulfated...

Direct Observation of Aβ Amyloid Fibril Growth and Inhibition

Amyloid fibril formation is a phenomenon common to many proteins and peptides, including amyloid β (Aβ) peptide associated with Alzheimer's disease. To clarify the mechanism of fibril formation and to create inhibitors, real-time monitoring of fibril growth is essential. Here, seed-dependent amyloid fibril growth of Aβ(1-40) was visualized in real-time at the single fibril level using total internal...
