Genetics of a novel starch utilisation pathway present in Klebsiella oxytoca.
A 14.3 kb DNA fragment from Klebsiella oxytoca M5a1 has been cloned and shown to provide Escherichia coli with the capacity for growth on alpha- and beta-cyclodextrins. This fragment is locatedExpand
The DevBCA exporter is essential for envelope formation in heterocysts of the cyanobacterium Anabaena sp. strain PCC 7120
The gene devA of the filamentous heterocyst‐forming cyanobacterium Anabaena sp. strain PCC 7120 encodes a protein with high similarity to ATP‐binding cassettes of ABC transporters. Mutant M7Expand
Sequence and mutational analysis of the devBCA gene cluster encoding a putative ABC transporter in the cyanobacterium Anabaena variabilis ATCC 29413.
The devBCA gene cluster (dev for development), shown to be essential for envelope formation in heterocysts of Anabaena sp. strain PCC 7120, was identified in the gene bank of a secondExpand
NtcA-dependent expression of the devBCA operon, encoding a heterocyst-specific ATP-binding cassette transporter in Anabaena spp.
The devBCA operon, encoding subunits of an ATP-binding cassette exporter, is essential for differentiation of N(2)-fixing heterocysts in Anabaena spp. Nitrogen deficiency-dependent transcription ofExpand
Characterization of devA, a gene required for the maturation of proheterocysts in the cyanobacterium Anabaena sp. strain PCC 7120.
Mutant M7, obtained by transposon mutagenesis of the cyanobacterium Anabaena sp. strain PCC 7120, is impaired in the development of mature heterocysts. Under aerobic conditions, the mutant is unableExpand
An ABC Exporter is Essential for the Localisation of Envelope Material in Heterocysts of Cyanobacteria
To perform oxygenic photosynthesis and fix dinitrogen simultaneously the filamentous cyanobacterium Anabaena sp. protects the extremely oxygen-sensitive nitrogenase by spatial separation of the twoExpand
