Isolation and Characterization of the Prolyl Aminopeptidase Gene (Pap) from Aeromonas Sobria: Comparison with the Bacillus Coagulans Enzyme1
J. Biochem. 116, 818-825 (1994) Isolation and Characterization of the Prolyl Aminopeptidase Gene (pap) from Aeromonas sobria: Comparison with the Bacillus coagulans Enzyme1 Ana Kitazono,* Atsuko Kitano,* Daisuke Tsuru,•õ and Tadashi Yoshimoto*,2 *School of Pharmaceutical Sciences , Nagasaki University, 1-14 Bunkyo-machi, Nagasaki, Nagasaki 852; and •õ Department of Applied Microbiology, Kumamoto Institute of Technology, 4-22-1 Ikeda, Kumamoto, Kumamoto 860 Received for publication, May 16, 1994 The Aeromonas sobria pap gene encoding prolyl aminopeptidase (PAP) was cloned. It consists of 425 codons and encodes a homotetrameric enzyme of 205kDa. The purified enzyme showed an almost absolute specificity for amino-terminal proline. Proline and hydroxyproline residues from many peptide and amide substrates could be easily removed, while no activity was detected for substrates having other amino terminals. The enzyme was very similar to that from Bacillus coagulans in many aspects, such as the strong inhibition caused by PCMB and the weak or no inhibition caused by DFP and chelators, respectively. However, these enzymes show only 15% identity in their amino acid sequences. Differences were also observed in their molecular weight, stability and activity toward some peptide substrates. When aligning the deduced amino acid sequence with known sequences from other microorganisms, conserved sequences were found at the amino-terminal region; the significance of these conserved regions is discussed. Based on the results of this work, and on the studies available to date, the occurrence of at least two types of PAPs is postulated. One group would be formed by the Bacillus, Neisseria, and Lactobacillus enzymes, and the other by enzymes such as the Aeromonas PAP. -
P-Glycoprotein, CYP3A, and Plasma Carboxylesterase Determine Brain and Blood Disposition of the Mtor Inhibitor Everolimus (Afinitor) in Mice

Sparidans3, Ka Lei Cheung4, Tatsuki Fukami5, Selvi Durmus1, Els Wagenaar1, Tsuyoshi Yokoi5, Bart J.M. van Vlijmen4, Jos H. Beijnen2,3, and Alfred H. Schinkel1 Abstract Purpose: To clarify the role of ABCB1, ABCG2, and CYP3A in blood and brain exposure of everolimus using knockout mouse models. À À À À À À À À Experimental Design: We used wild-type, Abcb1a/1b / , Abcg2 / , Abcb1a/1b;Abcg2 / , and Cyp3a / mice to study everolimus oral bioavailability and brain accumulation. Results: Following everolimus administration, brain concentrations and brain-to-liver ratios were À À À À À À substantially increased in Abcb1a/1b / and Abcb1a/1b;Abcg2 / , but not Abcg2 / mice. The fraction of everolimus located in the plasma compartment was highly increased in all knockout strains. In vitro, everolimus was rapidly degraded in wild-type but not knockout plasma. Carboxylesterase 1c (Ces1c), a plasma carboxylesterase gene, was highly upregulated (80-fold) in the liver of knockout mice relative to wild-type mice, and plasma Ces1c likely protected everolimus from degradation by binding and stabilizing it. This binding was prevented by preincubation with the carboxylesterase inhibitor BNPP. In vivo knockdown experiments confirmed the involvement of Ces1c in everolimus stabilization. Everolimus also markedly inhibited the hydrolysis of irinotecan and p-nitrophenyl acetate by mouse plasma carboxylesterase À À and recombinant human CES2, respectively. -

Metabolic Regulation by Lipid Activated Receptors by Maxwell A
Metabolic Regulation by Lipid Activated Receptors By Maxwell A Ruby A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy In Molecular & Biochemical Nutrition In the Graduate Division Of the University of California, Berkeley Committee in charge: Professor Marc K. Hellerstein, Chair Professor Ronald M. Krauss Professor George A. Brooks Professor Andreas Stahl Fall 2010 Abstract Metabolic Regulation by Lipid Activated Receptors By Maxwell Alexander Ruby Doctor of Philosophy in Molecular & Biochemical Nutrition University of California, Berkeley Professor Marc K. Hellerstein, Chair Obesity and related metabolic disorders have reached epidemic levels with dire public health consequences. Efforts to stem the tide focus on behavioral and pharmacological interventions. Several hypolipidemic pharmaceutical agents target endogenous lipid receptors, including the peroxisomal proliferator activated receptor α (PPAR α) and cannabinoid receptor 1 (CB1). To further the understanding of these clinically relevant receptors, we elucidated the biochemical basis of PPAR α activation by lipoprotein lipolysis products and the metabolic and transcriptional responses to elevated endocannabinoid signaling. PPAR α is activated by fatty acids and their derivatives in vitro. While several specific pathways have been implicated in the generation of PPAR α ligands, we focused on lipoprotein lipase mediated lipolysis of triglyceride rich lipoproteins. Fatty acids activated PPAR α similarly to VLDL lipolytic products. Unbound fatty acid concentration determined the extent of PPAR α activation. Lipolysis of VLDL, but not physiological unbound fatty acid concentrations, created the fatty acid uptake necessary to stimulate PPAR α. Consistent with a role for vascular lipases in the activation of PPAR α, administration of a lipase inhibitor (p-407) prevented PPAR α dependent induction of target genes in fasted mice. -

Date: 6-07-2018 A S M Mainul Hasan i Abstract Flowering is one of the key developmental process associated with the life cycle of plant and it is regulated by different environmental factors and endogenous cues. In the model species Arabidopsis thaliana a mobile protein, FLOWERING LOCUS T (FT) plays central role to mediate flowering time and expression of FT is regulated by photoperiod. While flowering mechanisms are well-understood in A. thaliana, knowledge about this process is limited in legume (family Fabaceae) which are the second major group of crops after cereals in satisfying the global demand for food and fodder. -
