Computational Investigation of Thiol-Based Redox Modifications in Proteins: Redox-Active Disulfides, Zn2+ Sites and Their Associations
THESIS SUBMITTED IN TOTAL FULFILLMENT OF THE REQUIREMENTS OF THE DEGREE OF DOCTOR OF PHILOSOPHY Computational investigation of thiol‐based redox modifications in proteins: redox‐active disulfides, 2+ Zn sites and their associations Application of tools of bioinformatics in health and disease Dhakshinari Vihara Kumari Hulugalle March 2013 Victor Chang Cardiac Research Institute School of Medical Sciences, Faculty of Medicine, University of New South Wales PLEASE TYPE THE UNIVERSITY OF NEW SOUTH WALES Thesis/Dissertation Sheet Surname or Family name: HULUGALLE First name: DHAKSHINARI Other name/s: VIHARA KUMARI PhD Abbreviation for degree as given in the University calendar: School: SCHOOL OF MEDICAL SCIENCES Faculty: MEDICINE Title: Computational investigation of thiol-based redox modifications in proteins: redox-active disulfides, Zn2+ sites and their associations Abstract 350 words maximum: (PLEASE TYPE) Thiol based redox signalling is an emerging area of research in protein science. Reversible disulfide bonding and Zn2+ expulsion are two important but less explored oxidative thiol modifications associated with redox signalling. They have numerous implications in health and disease. Three computational methods have previously been developed to predict redox-active disulfides in proteins: redox pair protein (RP) method, ‘forbidden disulfides’ (FD) method and torsional energy (TE) method. These methods and other tools of bioinformatics are used in my study to investigate redox-active disulfides, Zn2+ sites and the association between FDs and Zn fingers in protein structures. The first objective of my study was to apply the RP method to predict novel proteins containing likely redox-active disulfides. Over 300 novel RP proteins were found during this study. Significant conformational changes associated with disulfide redox activity in RP protein structures were also identified. -
Transcriptome Analysis of the Whitefly, Bemisia Tabaci MEAM1 During
Kaur et al. BMC Genomics (2017) 18:370 DOI 10.1186/s12864-017-3751-1 RESEARCH ARTICLE Open Access Transcriptome analysis of the whitefly, Bemisia tabaci MEAM1 during feeding on tomato infected with the crinivirus, Tomato chlorosis virus, identifies a temporal shift in gene expression and differential regulation of novel orphan genes Navneet Kaur1, Wenbo Chen2, Yi Zheng2, Daniel K. Hasegawa3, Kai-Shu Ling3, Zhangjun Fei2 and William M. Wintermantel1* Abstract Background: Whiteflies threaten agricultural crop production worldwide, are polyphagous in nature, and transmit hundreds of plant viruses. Little is known how whitefly gene expression is altered due to feeding on plants infected with a semipersistently transmitted virus. Tomato chlorosis virus (ToCV; genus Crinivirus, family Closteroviridae) is transmitted by the whitefly (Bemisia tabaci) in a semipersistent manner and infects several globally important agricultural and ornamental crops, including tomato. Results: To determine changes in global gene regulation in whiteflies after feeding on tomato plants infected with a crinivirus (ToCV), comparative transcriptomic analysis was performed using RNA-Seq on whitefly (Bemisia tabaci MEAM1) populations after 24, 48, and 72 h acquisition access periods on either ToCV-infected or uninfected tomatoes. Significant differences in gene expression were detected between whiteflies fed on ToCV-infected tomato and those fed on uninfected tomato among the three feeding time periods: 447 up-regulated and 542 down-regulated at 24 h, 4 up-regulated and 7 down-regulated at 48 h, and 50 up-regulated and 160 down-regulated at 72 h. Analysis revealed differential regulation of genes associated with metabolic pathways, signal transduction, transport and catabolism, receptors, glucose transporters, α-glucosidases, and the uric acid pathway in whiteflies fed on ToCV-infected tomatoes, as well as an abundance of differentially regulated novel orphan genes. -

Transcriptomic Data from Panarthropods Shed New Light on the Evolution of Insulator Binding Proteins in Insects Insect Insulator Proteins
Pauli et al. BMC Genomics (2016) 17:861 DOI 10.1186/s12864-016-3205-1 RESEARCHARTICLE Open Access Transcriptomic data from panarthropods shed new light on the evolution of insulator binding proteins in insects Insect insulator proteins Thomas Pauli1* , Lucia Vedder2, Daniel Dowling3, Malte Petersen1, Karen Meusemann1,4,5, Alexander Donath1, Ralph S. Peters6, Lars Podsiadlowski7, Christoph Mayer1, Shanlin Liu8,9, Xin Zhou10,11, Peter Heger12, Thomas Wiehe12, Lars Hering13, Georg Mayer13, Bernhard Misof1 and Oliver Niehuis1* Abstract Background: Body plan development in multi-cellular organisms is largely determined by homeotic genes. Expression of homeotic genes, in turn, is partially regulated by insulator binding proteins (IBPs). While only a few enhancer blocking IBPs have been identified in vertebrates, the common fruit fly Drosophila melanogaster harbors at least twelve different enhancer blocking IBPs. We screened recently compiled insect transcriptomes from the 1KITE project and genomic and transcriptomic data from public databases, aiming to trace the origin of IBPs in insects and other arthropods. Results: Our study shows that the last common ancestor of insects (Hexapoda) already possessed a substantial number of IBPs. Specifically, of the known twelve insect IBPs, at least three (i.e., CP190, Su(Hw), and CTCF) already existed prior to the evolution of insects. Furthermore we found GAF orthologs in early branching insect orders, including Zygentoma (silverfish and firebrats) and Diplura (two-pronged bristletails). Mod(mdg4) is most likely a derived feature of Neoptera, while Pita is likely an evolutionary novelty of holometabolous insects. Zw5 appears to be restricted to schizophoran flies, whereas BEAF-32, ZIPIC and the Elba complex, are probably unique to the genus Drosophila. -
