Zinc Compounds: Inorganic compounds that contain zinc as an integral part of the molecule.Xylariales: An order of ascomycetous FUNGI which includes many economically important plant parasites as well as saprophytes.Zinc Fingers: Motifs in DNA- and RNA-binding proteins whose amino acids are folded into a single structural unit around a zinc atom. In the classic zinc finger, one zinc atom is bound to two cysteines and two histidines. In between the cysteines and histidines are 12 residues which form a DNA binding fingertip. By variations in the composition of the sequences in the fingertip and the number and spacing of tandem repeats of the motif, zinc fingers can form a large number of different sequence specific binding sites.Zinc Sulfate: A compound given in the treatment of conditions associated with zinc deficiency such as acrodermatitis enteropathica. Externally, zinc sulfate is used as an astringent in lotions and eye drops. (Reynolds JEF(Ed): Martindale: The Extra Pharmacopoeia (electronic version).
