Role of the iron axial ligands of heme carrier HasA in heme uptake and release.
An additional sentence should be inserted in the right column at the end of the "Discussion." "In addition, Yukl et al. (49) and Jepkorir et al. (50) propose amodel in HasAp from Pseudomonas aeruginosa in which heme is initially bound by the Tyr to form a high spin heme protein complex before coordination of the His ligand upon closing of the His loop over the heme." These additions do not result in any change in the conclusions of the article. 49. Yukl, E. T. Jepkorir, G. Alontaga, A. Y. Pautsch, L. Rodriguez, J. C. Rivera, M. andMoenne Loccoz, P.
