Ubiquitous bacteria from the genus Oleispira drive oil degradation in the largest environment on Earth, the cold and deep sea. Here we report the genome sequence of Oleispira antarctica and show that compared with Alcanivorax borkumensis--the paradigm of mesophilic hydrocarbonoclastic bacteria--O. antarctica has a larger genome that has witnessed massive(More)
The activity of glutamate-oxalacetate and glutamate-pyruvate transaminases (GOT 2.6.1.1., GPT 2.6.1.2.) was determined in seedlings of normal and opaque-2 maize. The activity of these transaminases was determined in homozygotes +/+ and o2/o2, their F1 hybrid, in mixture of +/+ and +/o2 in S3F4 generation. The GOT and GPT activity in mutants opaque-2 was(More)
The activity of L-tryptophan synthase (TS, E.C.4.2.1.20) was comparedin vivo in seedlings of plants high in L-tryptophan (L-trp) (pea and kohlrabi) and low in this amino acid (maize). In maize the TS was studied both in the normal and in the opaque-2 genotype that forms an endosperm richer in essential amino acids. The activity of TS was determined on the(More)
The biosynthesis of L-tryptophan (L-trp) from anthranilic acid-14C (AA-14C) in. undamaged organs of the seedlings of kohlrabi and pea, with high L-trp content and ma ze plants, with low L-trp content was compared. As for maize the experiments were carried oiut with normal and opaque-2 phenotypes, both with the seedlings and with the ripening kernels. AA-14C(More)
