Conteúdo: |
Ureases, nickel-dependent enzymes that catalyze the hydrolysis of urea into ammonia and bicarbonate, are
widespread in plants, bacteria, and fungi. Previously, we cloned a cDNA encoding a Canavalia ensiformis urease
isoform named JBURE-II, corresponding to a putative smaller urease protein (78 kDa) when compared to
other plant ureases. Aiming to produce the recombinant protein, we obtained jbure-IIb, with different 3? and
5? ends, encoding a 90 kDa urease. Three peptides unique to the JBURE-II/-IIb protein were detected by mass
spectrometry in seed extracts, indicating that jbure-II/-IIb is a functional gene. Comparative modeling indicates
that JBURE-IIb urease has an overall shape almost identical to C. ensiformis major urease JBURE-I with
all residues critical for urease activity. The cDNA was cloned into the pET101 vector and the recombinant protein
was produced in Escherichia coli. The JBURE-IIb protein, although enzymatically inactive presumably due
to the absence of Ni atoms in its active site, impaired the growth of a phytopathogenic fungus and showed
entomotoxic properties, inhibiting diuresis of Rhodnius prolixus isolated Malpighian tubules, in concentrations
similar to those reported for JBURE-I and canatoxin. The antifungal and entomotoxic properties of the
recombinant JBURE-IIb apourease are consistent with a protective role of ureases in plants. |
