TP2, as purified from rat elongating spermatids, is shown here to contain 0.2 atoms of zinc bound per molecule of the protein by atomic absorption spectroscopy. On incubation with 10 渭M ZnCl2, invitro, and subs
We show that a previously uncharacterized zinc finger protein, ZBTB43, binds to and removes Z-DNA, preventing the formation of DNA double-strand breaks. By removing Z-DNA, ZBTB43 also promotes de novo DNA methylation at CG-containing purine–pyrimidine repeats in prospermatogonia. Therefore, the...
potentially using the molecule as a terminal electron acceptor in anaerobic respiration. Despite the recognized role of gut microorganisms in bilirubin reduction, the gut microbial enzyme that reduces bilirubin to urobilinogen, hereafter called bilirubin reductase, has remained undiscovered15. Multiple bilir...
(μ-2-ethoxyphenolato)-κ3O1,O2:O1;κ3O1:O1,O2-bis[(2-ethoxyphenolato-κ2O1,O2)(pyridine-κN)zinc(II)] toluene hemisolvate, [Zn2(C8H9O2)4(C5H5N)2]·0.5C7H8, crystallizes with two independent complex molecules located on inversion centres and one independent toluene solvent molecule ...
Presumably, they provide a flexible linker to the remainder of the molecule, i.e., an acidic region followed by an array of eight C2H2 zinc fingers in the case of Grauzone (Chen et al., 2000). The arrangement of the different ZAD structural elements is summarized in Figures 2A–2C and...
1.A zinc complex of a compound which has the chemical structure:where R═H and the compound is known as JBIR-141, or where RAH and the compound is known as JBIR-142, and the zinc complex is either a complex of JBIR-141 and a zinc ion and has the chemical formula C31H48N6O11Zn...
squamosa genome was assembled through sequencing of total DNA isolated from a plant grown from seed derived from commercially available A. squamosa fruit. Genomic DNA was sequenced by both long-read (PacBio (Menlo Park, CA) Single Molecule, Real-Time sequencing) and short read (Illumina (San ...
zinc, making detection by mass spectrometry of BMAA in its native form (m/z119 in positive ionization mode) difficult (Nunn et al.1989; Glover et al.2012). Derivatization of BMAA can prevent the spontaneous formation of metal adducts during analysis since the amine groups of the molecule are...
Does diacylglycerol serve as a signaling molecule in plants? Plant Signal Behav. 2012;7:472–5. 80. Stergiopoulos I, de Wit PJGM. Fungal effector proteins. Annu Rev Phytopathol. 2009;47:233–63. 81. Bauer R, Oberwinkler F, Vanky K. Ultrastructural markers and systematics in smut fungi ...
PIXE analyses of hamster protamines extracted under conditions that appear to at least partially preserve zinc binding also confirm that the majority of the metal is bound to protamine. In five of the species examined, sufficient zinc is present for each protamine 2 molecule to bind one zinc. ...
