In the present study, we have purified the group V phospholipase from the heart of cartilaginous fish stingray Dasyatis pastinaca and compared its biochemical properties with group IIA (sPLA(2)-IIA) and IB (sPLA(2)-IB) phospholipases previously purified from pancreas and intestine, respectively. Group V phospholipase (sPLA(2)-V) was purified to homogeneity by heat treatment, ammonium sulphate precipitation and RP-HPLC. The N-terminal sequence of the purified sPLA(2)-V exhibits a high degree of homology with those of mammal. The enzyme was found to be monomeric with a molecular mass estimation of 14 kDa. The specific activity of the purified enzyme, measured at pH 8 and 37 degrees C was 52 U/mg. Like sPLA(2)-IB and sPLA(2)-IIA, the sPLA(2)-V is found to be stable between pH 3 and 11 after 30 mm of incubation. The purified sPLA(2)-V retained 65% of its activity after 10 mm of incubation at 70 degrees C and it absolutely requires Ca2+ for enzymatic activity. In addition it displayed high tolerance to organic solvents. Kinetic parameters K-mapp, k(cat) and the deduced catalytic efficiency (k(cat)/K-mapp) of the purified group-V, -IB and -IIA PLA(2)s were determined using phosphatidylethanolamine (PE), phosphatidylcholine (PC) or phosphatidylserine (PS) as substrate. The three enzymes hydrolyze the zwiterionic PE and PC substrates more efficiently than anionic PS substrate. (C) 2013 Elsevier B.V. All rights reserved.

Effects of aging and diabetes on the deformation mechanisms and molecular structural characteristics of collagen fibrils under daily activity

Wei-Han Hui, Yen-Lin Chen, Shu-Wei Chang

Summary: Crosslinking affects the mechanical behavior and tissue metabolism of collagen-based tissues. Aging and diabetes alter the crosslinking type and density, thus changing tissue properties. High-connectivity enzymatic crosslinking and advanced-glycation end-products result in uniform deformation under daily activity, while low-connectivity enzymatic crosslinking does not. High-connectivity model displays more sliding, while AGEs induce instability in structures near the binding sites.
