Biochemistry. In the article “An Erp60-like protein from the filarial parasite Dirofilaria immitis has both transglutaminase and protein disulfide isomerase activity” by Ramaswamy Chandrashekar, Naotoshi Tsuji, Tony Morales, Victor Ozols, and Kapil Mehta, which appeared in number 2, January 20, 1998, of Proc. Natl. Acad. Sci. USA (95, 531–536), the authors inadvertently cited the wrong GenBank accession numbers for four database sequences in the figure legend of a dendrogram (Fig. 3b) on page 534. The correct accession numbers are shown in the table below.
