Three members of a family acquired psittacosis after exposure to a wild pigeon. Each of the patients had pulmonary infiltrates, prominent headache, abdominal complaints, and serologic evidence for infection with Chlamydia psittaci. Of 759 cases of psittacosis reported to the Centers for Disease Control for the period of 1974 to 1981, some 75 (10 percent) were associated with pigeons. Fifty-two ...

Initiation factors IF2 in bacteria and eIF2 in eukaryotes are GTPases that bind Met-tRNA(i)(Met) to the small ribosomal subunit. eIF5B, the eukaryotic ortholog of IF2, is a GTPase that promotes ribosomal subunit joining. Here we show that eIF5B GTPase activity is required for protein synthesis. Mutation of the conserved Asp-759 in human eIF5B GTP-binding domain to Asn converts eIF5B to an XTPas...
