Sequence and expression in Escherichia coli of a Mycoplasma hominis gene encoding elongation factor Tu.

ABSTRACT

We describe the molecular cloning and the complete nucleotide (nt) sequence of a Mycoplasma hominis gene common to a broad range of Mycoplasma species, as defined by hybridization analysis with the cloned gene. Production of M. hominis protein in Escherichia coli was assayed by use of a monoclonal antibody. The nt sequence analysis revealed a 1194-bp open reading frame that could encode a 43 516-Da protein. Computer-aided sequence comparison indicated that the gene codes for elongation factor Tu.
