Posttranscriptional modification of tRNA in psychrophilic bacteria.
Posttranscriptional modification in tRNA is known to play a multiplicity of functional roles, including maintenance of tertiary structure and cellular adaptation to environmental factors such as temperature. Nucleoside modification has been studied in unfractionated tRNA from three psychrophilic bacteria (ANT-300 and Vibrio sp. strains 5710 and 29-6) and one psychrotrophic bacterium (Lactobacil...
متن کاملGrowth of psychrophilic bacteria.
On the basis of the temperature range in which growth can occur, bacteria are usually divided into 3 groups, namely: thermophiles, mesophiles, and psychrophiles (sometimes called cryophiles or rhigophiles). Thermophiles have temperature optima (generally quite close to temperature maxima) 10 to 25 degrees above the temperature optima of mesophiles. Thermophiles and mesophiles are easily disting...

Upadhyay, J. (Washington State University, Pullman) and J. L. Stokes. Anaerobic growth of psychrophilic bacteria. J. Bacteriol. 83:270-275. 1962.-Facultatively anaerobic psychrophilic bacteria are widely distributed in nature and can be readily isolated from a variety of foods, soil, sewage, and other habitats. Strictly anaerobic psychrophiles, however, could not be isolated. Temperature and ox...
متن کاملAlternative Tertiary Structure of tRNA for Recognition by a Posttranscriptional Modification Enzyme
Transfer RNA (tRNA) canonically has the clover-leaf secondary structure with the acceptor, D, anticodon, and T arms, which are folded into the L-shaped tertiary structure. To strengthen the L form, posttranscriptional modifications occur on nucleotides buried within the core, but the modification enzymes are paradoxically inaccessible to them in the L form. In this study, we determined the crys...
متن کاملPredicting Mitochondrial tRNA Modification
M itochondria are integral to proper cell function, and mutations in its small genome (mtDNA) are associated with many diseases, along with the progression of normal aging [9]. While mtDNA has been extensively studied, not much is known about transcriptional variations of mitochondrial genes [3]. Recently, tRNA modifications have been the focus of intense study owing to their putative role in d...
