Incorporation of L-methionine-methyl-14C into gentamicins.
Gentamicin C complex, produced by Micromonospora purpurea1*2), is composed of three components, Cla, C2 and Q (Fig. 1). These components are methylaminoglycosides, which are distinct from other related antibiotics such as the kanamycins, neomycinsand paromomycins. As seen in Fig. 1, gentamicins Cla, C2, and Q possess one C-methyl and one N-methyl group, two C-methyl and one N-methyl groups and ...
متن کاملIncorporation of L-methionine-methyl-14C into gentamicins. II. Large-scale preparation of methyl-14C-gentamicins.
Methyl-14C-gentamicins were prepared from incubation of Micromonospora purpurea in the presence of added methyl-'4C-L-methionine, and products with high specific radioactivity were isolated in satisfactory yields. In the previous paper1), we have shown in shake flask fermentation a high and selective incorporation of radioactivity from methyl-14C-L-methionine into gentamicins. Consequently, we ...
متن کاملThe incorporation of labeled methionine into protein by pituitary tissue.
In recent years numerous reports on the uptake of labeled amino acids by the proteins of tissue preparations have appeared. Various amino acids have been used, and the reaction has been shown to occur in tissue slices (l-4), homogenates (5), and in resting bacteria (6, 7). Considerable evidence has accumulated, indicating that this labeling of protein represents a synthesis of peptide bonds. In...
متن کامل[Methyl-14C]-choline incorporation into nude mice bearing tumor xenografts-correlation with [methyl-3H]-thymidine: A pilot study
Background: Many in vitro studies suggested that choline incorporation into many types of tumors is related to cell proliferation. Whether in vivo choline incorporation is related also to cell proliferation or not was my question. Therefore, the aim of this pilot study was to investigate the relationship of in vivo [methyl- 14C]-choline incorporation and in vivo [methyl-3H]- thymidine incorpora...
متن کامل8-Methyl-2′-deoxyguanosine incorporation into parallel DNA quadruplex structures
This paper concerns the Circular Dichroism (CD) and Nuclear Magnetic Resonance (NMR) structural studies of the quadruple helix arrangements adopted by three tailored oligodeoxyribonucleotide analogues, namely d(TG(Me)GGT), d(TGG(Me)GT) and d(TGGG(Me)T), where dG(Me) represents a 8-methyl-2'-deoxyguanosine residue. The results of this study clearly demonstrate that the effects of the incorporati...
