Keenleyside W, Clarke A, Whitfield C
J Bacteriol . 2000 Dec; 183(1):77-85. PMID: 11114903
Synthesis of the O:54 O antigen of Salmonella enterica is initiated by the nonprocessive glycosyl transferase WbbE, assigned to family 2 of the glycosyl transferase enzymes (GT2). GT2 enzymes possess...

Clarke A, Francis D, Keenleyside W
FEMS Microbiol Lett . 1996 Dec; 145(2):201-7. PMID: 8961557
The prevalence of aac(2')-Ia, a gene coding for gentamicin 2'-N-acetyltransferase in Providencia stuartii, among species of the Proteeae was investigated to determine if it is a common resistance factor and...

Keenleyside W, Whitfield C
J Biol Chem . 1996 Nov; 271(45):28581-92. PMID: 8910488
The plasmid-encoded gene cluster for O:54 O-polysaccharide synthesis in Salmonella enterica serovar Borreze (rfbO:54) contains three genes that direct synthesis of a ManNAc homopolymer with alternating beta1,3 and beta1,4 linkages....

Whitfield C, Keenleyside W
J Ind Microbiol . 1995 Oct; 15(4):361-71. PMID: 8605073
Bacterial surface polysaccharides fulfill a number of important roles in cell-cell interactions, survival in natural environments, and formation of biofilms. Consequently, the mechanisms involved in regulation of extracellular polysaccharides are...

Clarke B, Bronner D, Keenleyside W, Severn W, Richards J, Whitfield C
J Bacteriol . 1995 Oct; 177(19):5411-8. PMID: 7559323
The 6.6-kb rfb gene cluster from Klebsiella pneumoniae serotype O1 (rfbKpO1) contains six genes whose products are required for the biosynthesis of a lipopolysaccharide O antigen with the following repeating...
6.
Keenleyside W, Whitfield C
J Bacteriol . 1995 Sep; 177(18):5247-53. PMID: 7545154
Plasmid pWQ799 is a 6.9-kb plasmid isolated from Salmonella enterica serovar Borreze. Our previous studies have shown that the plasmid contains a functional biosynthetic gene cluster for the expression of...
7.
Keenleyside W, Perry M, MacLean L, Poppe C, Whitfield C
Mol Microbiol . 1994 Feb; 11(3):437-48. PMID: 7512186
Previous studies demonstrated that the presence of a 7-8 kb plasmid is correlated with expression of the lipopolysaccharide (LPS) O:54 antigen in several Salmonella enterica serovars. In this study, a...

MacLachlan P, Keenleyside W, Dodgson C, Whitfield C
J Bacteriol . 1993 Dec; 175(23):7515-22. PMID: 8244920
Escherichia coli K antigens (capsular polysaccharides) are divided into two broad classes, designated groups I and II, on the basis of a number of chemical, physical, and genetic criteria. Group...

Keenleyside W, Bronner D, Jann K, JANN B, Whitfield C
J Bacteriol . 1993 Oct; 175(20):6725-30. PMID: 8407850
In Escherichia coli K-12, the rcsA and rcsB gene products are positive regulators in expression of the slime polysaccharide colanic acid. We have previously demonstrated the presence of rcsA sequences...

Jayaratne P, Keenleyside W, MacLachlan P, Dodgson C, Whitfield C
J Bacteriol . 1993 Sep; 175(17):5384-94. PMID: 8366025
In Escherichia coli K-12, RcsC and RcsB are thought to act as the sensor and effector components, respectively, of a two-component regulatory system which regulates expression of the slime polysaccharide...
