Purpose. To analyse the taxonomic composition of subtropical plants Khorol Botanical Garden collection. Results. Taxonomic collection, consisting 25 species: Actinidia chinensis Planch., Asimina triloba (L.) Dunal, Camellia sinensis Kuntze, Chaenomeles ×californica Clarke ex Weber, Citrus trifoliata L., Cormus domestica Crataegus azarolus opaca Hooker & Arn., Cydonia oblonga Mill., Diospyro...
From mutational analysis of the 3'-terminal hairpin of turnip yellow mosaic virus (TYMV) RNA and use of nonstructured C-rich RNA templates, we conclude that the main determinant in the tRNA-like structure of TYMV RNA for initiation of minus-strand synthesis by the viral RNA-dependent RNA polymerase (RdRp) is the non-base-paired 3' ACC(A) end. Base pairing of this 3' end reduces the transcriptio...
In Mycobacterium tuberculosis, the carboxylation of acetyl coenzyme A (acetyl-CoA) to produce malonyl-CoA, a building block in long-chain fatty acid biosynthesis, is catalyzed by two enzymes working sequentially: a biotin carboxylase (AccA) and a carboxyltransferase (AccD). While the exact roles of the three different biotin carboxylases (AccA1 to -3) and the six carboxyltransferases (AccD1 to ...
Periplasmic binding proteins (PBPs) in association with ABC transporters select and import a wide variety of ligands into bacterial cytoplasm. They can also take up toxic molecules, as observed in the case of the phytopathogen Agrobacterium tumefaciens strain C58. This organism contains a PBP called AccA that mediates the import of the antibiotic agrocin 84, as well as the opine agrocinopine A ...
Food fortifi cation with synthetic folic acid (pteroyl monoglutamic acid) remains a source of debate in terms of benefi t versus issues of safety and consumer choice. Several countries have adopted mandatory folic acid fortifi cation. A decision to proceed in Australasia was made in June, 2007. We report the case of a woman who had three episodes of type I hypersensitivity, including ana phylax...
