Arginine, also known as l-arginine (symbol Arg or R), is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group, an α-carboxylic acid group, and a side chain consisting of a 3-carbon aliphatic straight chain ending in a guanidino group. At physiological pH, the carboxylic acid is deprotonated (−COO⁻), the amino group is protonated (−NH₃⁺), and the guanidino group is also protonated to give the guanidinium form (-C-(NH₂)₂⁺), making arginine a charged, aliphatic amino acid. It is the precursor for the biosynthesis of nitric oxide. It is encoded by the codons CGU, CGC, CGA, CGG, AGA, and AGG.
Compound and method for treating myotonic dystrophy

The oligonucleotide has 8-30 bases, with at least 8 contiguous bases being complementary to the polyCUG or polyCCUG repeats in the 3′UTR region of dystrophia myotonica protein kinase (DMPK) mRNA in DM1 or DM2, respectively. Conjugated to the oligonucleotide is a cell-penetrating peptide having the sequence (RXRR(B / X)R)2XB, where R is arginine; B is β-alanine; and each X is —C(O)—(CH2)n—NH—, where n is 4-6. The antisense compound is effective to selectively block the sequestration of muscleblind-like 1 protein (MBNL1) and / or CUGBP, in heart and quadricep muscle in a myotonic dystrophy animal model.

The present invention relates to 25 hitherto undescribed genes of B. licheniformis and gene products derived therefrom and all sufficiently homologous nucleic acids and proteins thereof. They occur in five different metabolic pathways for the formation of odorous substances. The metabolic pathways in question are for the synthesis of: 1) isovalerian acid (as part of the catabolism of leucine), 2) 2-methylbutyric acid and / or isobutyric acid (as part of the catabolism of valine and / or isoleucine), 3) butanol and / or butyric acid (as part of the metabolism of butyric acid), 4) propyl acid (as part of the metabolism of propionate) and / or 5) cadaverine and / or putrescine (as parts of the catabolism of lysine and / or arginine). The identification of these genes allows biotechnological production methods to be developed that are improved to the extent that, to assist these nucleic acids, the formation of the odorous substances synthesized via these metabolic pathways can be reduced by deactivating the corresponding genes in the micro-organism used for the biotechnological production. In addition, these gene products are thus available for preparing reactions or for methods according to their respective biochemical properties.
