    Notes: Summary An enzyme that catalyzes 2′-O-phosphorylation of oleandomycin and several other macrolide antibiotics has been purified approximately 47-fold from cell-free extracts ofStreptomyces coelicolor Müller, NRRL 3532 (UC™ 5240). The reaction product was verified as being oleandomycin-2′-O-phosphate by mass spectrometry. As a result of purification, the enzyme was separated from two lincosaminide inactivating enzyme activities also present in the cell-free extract.

    Preliminary Ar-40/Ar-39 age spectrum and laser probe dating of the M1 core of the Manson Impact Structure, Iowa: A K-T boundary crater candidate (1993)

    Description: Preliminary Ar-40/Ar-39 age spectrum and laser probe dating results from new drill core from the 35-km-diameter Manson Impact Structure (MIS), Iowa indicates a reasonable possibility that the MIS is a Cretaceous-Tertiary (K-T) boundary impact event. Several different types of samples from a melt-matrix breccia, a unit of apparent crater fill intersected by the M1 core, were analyzed. Ar-40/Ar-39 results from these samples indicate a maximum age for the MIS of about 65.4 plus or minus 0.4(2 sigma) Ma. Petrographic analyses of the samples indicate a high probability that all the dated samples from the melt-matrix breccia contain relict grains that were not entirely melted or degassed at the time of impact, suggesting that the actual age of the MIS could be somewhat younger than our preliminary results indicate. The results are consistent with a previously published age estimate of shocked microcline from the MIS central uplift of 65.7 plus or minus 1.0 Ma.
