Characterization of a Ca(II)-, Mineral-Interactive Poly-electrolyte Sequence from the Adhesive ElastomericBiomineralization Protein, Lustrin ABrandon A. Wustman, James C. Weaver, Daniel E.Morse, and John Spencer Evans* Langmuir 2003, 19,9373-9381.

In the Materials and Methods section under thesubheading Crystal Growth Interaction Experiments, theactual polypeptide concentration range utilized in thegeologic calcite overgrowth experiments should read as1.1 × 10-6, 3.3 × 10-6, 1.7 × 10-5, 3.3 × 10-5, 1.7 × 10-5,and 3.3 × 10-4 M. Under the subheading, Solid-State 1HMagic-Angle Spinning (MAS) NMR Spectroscopy, theconcentration of D4 polypeptide utilized in this assayshould read as 3.3 × 10-4 M.

Likewise, in the Results section, the polypeptide con-centrations reported in the legend to Figure 6 requirecorrection. The correct figure legend and polypeptideconcentrations are presented below.Figure 6.
