Abstract
Two arginyl-transfer ribonucleic acid (tRNA) synthetase (EC 6.1.1.13, arginine: ribonucleic acid ligase adenosine monophosphate) activities were found in extracts of Escherichia coli strains AB1132 and NP2. The two arginyl-tRNA synthetase activities in extracts of strain AB1132 were found to be separable by diethylaminoethyl-cellulose column chromatography, Sephadex column fractionation, and by sucrose density gradient centrifugation. In addition, in the standard assay using extracts of strain AB1132 there were two pH optima for arginyl-tRNA synthetase activity. Furthermore, when arginyl-tRNA synthetase of strain NP2 was fractionated by hydroxylapatite column chromatography, two activities were observed which were similar to those of strain AB1132.

Abstract
1. Cell-free protein synthesis was studied in striated and smooth muscles in an attempt to elucidate the primary genetic defect in polymyopathic hamsters. 2. When washed membrane-free polyribosomes from myopathic and control heart muscle were individually recombined with pH5 enzymes from both types of animals, the pH5 enzymes from myopathic muscle were less active in polypeptide synthesis than those from controls, irrespective of the source of polyribosomes. 3. The same defect was present in skeletal-muscle preparations. 4. Both the initial rate and the maximum extent of incorporation were affected in the defective preparations from myopathic muscle. 5. Concentration differences, with respect to total protein and RNA, were not responsible. 6. Preincubation of the pH5 enzymes resulted in a greater degree of inhibition. 7. The defect in the pH5 enzymes from myopathic muscle was also expressed in poly(U)-directed polyphenylalanine synthesis. 8. Acid proteinase activity in extracts of control and myopathic muscle was the same but general ribonuclease activity in the latter extracts was higher. 9. The defect was also present when both types of pH5 enzymes were prepared in the presence of the ribonuclease-asborbent bentonite. 10. pH5 enzymes from uterine smooth muscle, brains and livers of myopathic animals were similarly affected in homologous and heterologous combinations. 11. It is concluded that the general tissue defect is both qualitative and quantitative in nature, implying that there is a shortage of some essential soluble component in the pH5 fraction which is accompanied by the presence of an altered substituent. This prevents the attainment of extents of polypeptide synthesis in vitro obtained in control extracts from unaffected animals.

Abstract
1. Different reaction steps involved in protein synthesis were studied in skeletal muscles from control and myopathic hamsters. 2. There was no difference between partially purified aminoacyl-tRNA synthetases from myopathic and control animals in yield or catalytic activity, as tested with exogenous deacylated tRNA. 3. However, isolated deacylated tRNA from myopathic muscle was aminoacylated by these synthetases to a lesser extent than that derived from control muscle. 4. Addition of deacylated tRNA isolated from control muscle improved the performance of pH5 enzymes from myopathic muscle in polypeptide synthesis on homologous polyribosomes; tRNA isolated from myopathic animals did not. 5. Preparation of extracts from both types of animals in the presence of the ribonuclease-absorbent bentonite led to an increased capacity of endogenous tRNA to accept amino acids in pH5 enzymes prepared from normal and abnormal tissue, but the difference between the two systems remained the same. 6. Total tRNA nucleotidyltransferase activity, tested with twice-pyrophosphorolysed rat liver tRNA, was identical in both extracts. 7. Added tRNA nucleotidyltransferase incorporated more AMP and CMP into endogenous tRNA with the pH5 enzyme from myopathic muscle than with that from control muscle. 8. Preincubation of deacylated tRNA from myopathic muscle with ATP, CTP and tRNA nucleotidyltransferase more than doubled its subsequent aminoacyl-acceptor activity, and halved the extent of the defect relative to aminoacylation of control tRNA similarly treated. Endogenous tRNA in pH5 enzyme preparations behaved likewise. 9. It is suggested that a 3'-exonuclease in myopathic muscles attacks tRNA molecules in such a way that some of them remain substrates for tRNA nucleotidyltransferase, which may incorporate into RNA not only AMP and CMP, but also GMP. 10. Cell-free protein synthesis in preparations from myopathic hamster muscles is limited by the supply of intact tRNA molecules.

Abstract
A mutant of Escherichia coli K-12 was examined which has growth medium-dependent lysyl-transfer ribonucleic acid (tRNA) ligase activity. In minimal medium or 0.5% yeast extract, the activity of the enzyme in the mutant strain was 5 to 10% of wild type. However, when the mutant was grown in a highly enriched medium, such as AC broth (Difco), the activity of the mutant ligase increased 10- to 20-fold. We found that the supplementation of 0.5% yeast extract by l-alanine plus d-fructose replaces the need for the highly enriched medium. Fructose plus l-leucine and fructose plus l-alpha-amino-n-butyric acid were also stimulatory, but not as effective as fructose and alanine. With minimal medium, a combination of carbohydrate (fructose or glucose) plus alanine and leucine was required to replace the enriched medium. The most effective combination was fructose, glucose, alanine, and leucine. Lysyl-tRNA ligase was stimulated 1.5 to 2-fold in the wild-type strain or Hfr H (Hayes) by fructose plus alanine when these strains were cultured in 0.5% yeast extract. Experiments employing the combined technique of density labeling with D(2)O and isopycnic centrifugation in cesium chloride indicated that the increased activity of lysyl-tRNA ligase observed in AC broth or in the presence of fructose, glucose, alanine, and leucine is due to the synthesis of new enzyme.

Abstract
The purpose of the study was the estimation of the changes in the activity of 20 individual sRNA amino acyl synthetases in the newborn, 12th, 30th, 48th and 180th days old rabbit brain. The investigations showed that the highest enzyme activity was found in the pH 5 fraction obtained from the CNS of newborn rabbits. In the further period of brain’s development there was a decline in the activity of amino acyl sRNA synthetases beginning from the 12th day of extrauterine life and continuing until the animals were 48 days old, when the activity approximated that measured in the adult rabbit brain. The activity of these enzymes in the developing brain was higher in the cerebral cortex than in the white matter.

Abstract
Protein synthesis by whole cells of two psychrophilic bacteria, Bacillus psychrophilus and Bacillus insolitus, directly corresponded to the growth of these organisms at 5, 20 and 30C, with a smaller total amount of growth and protein synthesis occurring at 30C than at 20C. When the effect of temperature on protein synthesis was examined using extracts, the capability to carry out poly U directed incorporation of 14C-L-phenylalanine into protein was inhibited by 30C as compared to 5C. The temperature sensitivity of the cell-free protein synthesizing systems was not due to the presence of heat-sensitive aminoacyl-tRNA synthetases. Investigation of the effect of separately heating at 30C washed ribosome (W-RIB) and supernatant (IS-100) fractions prepared from these microorganisms, followed by recombination and reaction at 15C, showed that the temperature sensitivity of the protein synthesis resided in the ribosomal fraction of the cells
