Pseudomonas putida aggressively colonizes root surfaces and is agglutinated by a root surface glycoprotein. Mutants of P. putida derived chemically or by Tn5 insertion demonstrated enhanced or decreased agglutinability. Two nonagglutinable Tn5 mutants (Agg) and two mutants with enhanced agglutinability (Agg) possessed Tn5 in unique restriction sites. Agg(More)
Esterase-6 (EST 6; carboxylic-ester hydrolase; EC 3.1.1.1) from Drosophila melanogaster was purified to homogenity. Purified enzyme occurs as two closely moving isozymes, slow (EST 6S) and fast (EST 6F), on native polyacrylamide gel electrophoresis. Except for slight differences in their mobility, the two isozymes share similar molecular and catalytic(More)
Pseudomonas putida aggressively colonizes root surfaces and is agglutinated by a root surface glycoprotein. Mutants of P. putida derived chemically or by Tn5 insertion demonstrated enhanced or decreased agglutinability. Two nonagglutinable TnS mutants (Agg-) and two mutants with enhanced agglutinability (AggS) possessed TnS in unique restriction sites.(More)
The esterase 6 locus in Drosophila melanogaster is the structural gene for a carboxylesterase (E.C. 3.1.1.1) and is polymorphic for two major electrophoretic variants (slow and fast). Isogenic lines containing X chromosomes extracted from natural populations and substituted into a common genetic background were used to detect unlinked factors that affect(More)
