Abstract

Polyaspartate domains are a prominent feature of proteins associated with biogenic carbonates and have been implicated in modifying crystal morphology through specific interactions with step edges. Here, we show that the morphology and growth kinetics of calcite are modified in a systematic way when a series of poly- l -aspartates, Asp 1 - 6, are introduced into solution. In-situ measurements of step propagation rates by atomic force microscopy reveal these effects are strongly chain-length dependent and specific to the crystallographically distinct, obtuse and acute step types. Direct observations of differential roughening and rounding of the step edges demonstrate that, while Asp 1 and Asp 2 have stronger effects on acute step edges, a crossover occurs for the longer Asp 4,5,6 peptides that preferentially affect obtuse steps. Independent analysis of Asp n −step edge interactions by semiempirical quantum mechanical modeling gives estimates of aspartate−step edge binding energies and predicts that the crossover should occur at n = 2. The switch occurs because, upon Asp n binding, the energy required to dehydrate acute steps is greater than that at the obtuse steps when n = 3−6. Step velocity measurements show that the concentration of Asp n needed to stop growth scales exponentially and inversely with the calculated binding energies. A simple model of Asp n adsorption to the steps is derived from these results. These findings suggest a process by which small fluctuations in primary structure in proteins can control calcite shape.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
