Construction of a cosmid library of Spirulina platensis as an approach to DNA physical mapping.
No full textA Spirulina platensis gene library has been constructed using cosmid vector pMMB34. The cosmid bank was controlled for its random gene distribution by colony hybridization. Genes were identified using either homologous or heterologous probes of genes involved in photosynthesis (large and small subunit of d-ribulose 1,5-bisphosphate carboxylase, 32 kDa thylakoid protein, α, β subunits of C-phycocyanin) and protein synthesis (elongation factors EF-Tu, EF-G)
Phylogenetic depth of the S10 and spc operons: cloning and sequencing of a ribosomal protein gene cluster from the extremely termophilic bacterium Thermotoga maritima
No full textAltered methionyl-tRNA synthetase in a Spirulina platensis mutant resistant to ethionine.
No full textCompared with the parental strain, a Spirulina platensis mutant that is resistant to ethionine incorporated methionine into protein at a reduced rate, whereas ethionine incorporation was practically nil. The methionyl-tRNA synthetase present in crude extracts from the resistant strain showed a reduced affinity for methionine and ethionine
