1.
Toukdarian A, Helinski D
Gene
. 1998 Dec;
223(1-2):205-11.
PMID: 9858734
Copy-number regulation of the broad-host-range plasmid RK2 is dependent on the plasmid-encoded initiator protein, TrfA, and the RK2 origin of replication. The handcuffing model for copy-number control proposes that TrfA-bound...

Blasina A, Kittell B, Toukdarian A, Helinski D
Proc Natl Acad Sci U S A
. 1996 Apr;
93(8):3559-64.
PMID: 8622975
The broad host range plasmid RK2 replicates and regulates its copy number in a wide range of Gram-negative bacteria. The plasmid-encoded trans-acting replication protein TrfA and the origin of replication...

Toukdarian A, Helinski D, Perri S
J Biol Chem
. 1996 Mar;
271(12):7072-8.
PMID: 8636140
The TrfA protein encoded by the broad host range bacterial plasmid RK2 specifically binds to eight direct repeats (iterons) present at the plasmid replication origin to initiate DNA replication. Purified...

Cereghino J, Helinski D, Toukdarian A
Plasmid
. 1994 Jan;
31(1):89-99.
PMID: 8171128
An in vivo screen was developed for the identification of mutants of the RK2 replication initiation protein, TrfA, that were altered in their binding to the iterons within the plasmid...

Toukdarian A, Lidstrom M
J Gen Microbiol
. 1984 Jul;
130(7):1827-37.
PMID: 6432952
A new obligate methanotroph was isolated and characterized. It was classified as a 'Methylosinus' species and named 'Methylosinus' sp. strain 6. Nitrogen metabolism in 'Methylosinus' 6 was found to be...

Toukdarian A, Lidstrom M
J Bacteriol
. 1984 Mar;
157(3):979-83.
PMID: 6321452
We describe here a method for constructing mutants in bacteria that are not amenable to mutant isolation by conventional means. A one-step marker exchange procedure was used to construct nitrogen...

Toukdarian A, Lidstrom M
J Bacteriol
. 1984 Mar;
157(3):925-30.
PMID: 6321444
DNA isolated from two diazotrophic methylotrophs, the obligate methanotroph Methylosinus sp. strain 6 and the methanol autotroph Xanthobacter sp. H4-14, hybridized to DNA fragments encoding nitrogen fixation (nif) genes from...

Lidstrom M, Wopat A, Nunn D, Toukdarian A
Basic Life Sci
. 1984 Jan;
28:319-30.
PMID: 6422924
Methanotrophs have interesting properties concerning the oxidation and dehalogenation of both straight-chain and aromatic hydrocarbons. However, the potential of these bacteria in the degradation of these compounds cannot be assessed...
