Aerobiology Over Antarctica – A New Initiative for Atmospheric Ecology
The role of aerial dispersal in shaping patterns of biodiversity remains poorly understood, mainly due to a lack of coordinated efforts in gathering data at appropriate temporal and spatial scales.Expand

A novel Pseudomonas putida strain with high levels of hydantoin-converting activity, producing l-amino acids
Abstract Optically pure chiral amino acids and their derivatives can be efficiently synthesised by the biocatalytic conversion of 5-substituted hydantoins in reactions catalysed by stereo-selectiveExpand

Diversity of Bacterial Communities Associated with the Indian Ocean Sponge Tsitsikamma favus That Contains the Bioactive Pyrroloiminoquinones, Tsitsikammamine A and B
Tsitsikamma favus is a latrunculid sponge endemic to the coast of South Africa that produces unique pyrroloiminoquinones known as tsitsikammamines. Wakayin and makaluvamine A are structurally similarExpand

Production of enantiomerically pure amino acids: characterisation of South African hydantoinases and hydantoinase-producing bacteria
Abstract Chiral amino acid derivatives can be synthesised by the biocatalytic conversion of substituted hydantoins using microbial enzymes or resting cells: a hydantoinase performs the ring-openingExpand

The effect of the location of the proteic post-segregational stability system within the replicon of plasmid pTF-FC2 on the fine regulation of plasmid replication.
The broad host-range IncQ-2 family plasmid, pTF-FC2, is a mobilizable, medium copy number plasmid that lacks an active partitioning system. Plasmid stability is enhanced by a toxin-antitoxin (TA)Expand

Mutational analysis of the hydantoin hydrolysis pathway in Pseudomonas putida RU-KM3S
The biocatalytic conversion of 5-mono-substituted hydantoins to the corresponding d-amino acids or l-amino acids involves first the hydrolysis of hydantoin to a N-carbamoylamino acid by anExpand

Characterization of the hydantoin-hydrolysing system of Pseudomonas putida RU-KM3s
The biocatalytic conversion of 5-monosubstituted hydantoin derivatives to optically pure amino acids involves two reaction steps: the hydrolysis of hydantoin to N-carbamylamino acid by anExpand
