Molecular basis for the production of cyclic peptides by plant asparaginyl endopeptidases.
Mark A. Jackson,Edward K. Gilding,Thomas Shafee,Karen S. Harris,Quentin Kaas,Simon Poon,Kuok Yap,H Jia,Rosemary F. Guarino,Lai Yue Chan,Thomas Durek,Marilyn A. Anderson,David J. Craik +12 more
TL;DR: Comparisons of diverse plant AEPs are compared by combining molecular modeling, sequence space analysis, and functional testing, finding that changes within the substrate-binding pocket and an adjacent loop, here named the “marker of ligase activity”, together play a key role for AEP ligase efficiency.
Field resistance to Fusarium oxysporum and Verticillium dahliae in transgenic cotton expressing the plant defensin NaD1
Yolanda Maria Gaspar,James A. McKenna,James A. McKenna,Bruce S. McGinness,Jillian M. Hinch,Simon Poon,Simon Poon,Angela A. Connelly,Marilyn A. Anderson,Robyn Louise Heath +9 more
TL;DR: Expression of the plant defensin NaD1 in transgenic cotton plants increases plant survival, disease tolerance, and yield when grown in soil naturally infested with Fusarium oxysporum and Verticillium dahliae.
A Chimeric Arabinogalactan Protein Promotes Somatic Embryogenesis in Cotton Cell Culture
TL;DR: This work cloned a full-length complementary DNA (cotton PHYTOCYANIN-LIKE ARABINOGALACTAN-PROTEIN1 [GhPLA1] that encoded the protein backbone of an AGP in the active fraction and purified and analyzed a single glycosylated AGP, demonstrating that this chimeric AGP promotes cotton SE.
Co-expression of a cyclizing asparaginyl endopeptidase enables efficient production of cyclic peptides in planta.
Simon Poon,Karen S. Harris,Mark A. Jackson,Owen C. McCorkelle,Edward K. Gilding,Thomas Durek,Nicole L. van der Weerden,David J. Craik,Marilyn A. Anderson +8 more
TL;DR: Backbone-cyclized peptides, which have applications in the pharmaceutical and agricultural industries, can be made efficiently in plants by co-expressing them with a cyclizing enzyme.
Effect of denaturants on the emulsifying activity of proteins.
TL;DR: The relationship between protein flexibility and emulsifying activity was investigated and depended on the relative importance of disulfide bonds and noncovalent interactions in stabilizing the native conformation of each protein.
