    • Erickson, Rick (1990)
      The Asp15-->Ala mutant of ribonuclease T1 (RNase T1) was constructed by site-directed mutagenesis, cloned and expressed in Escherichia coli. This mutant was synthesized to determine whether or not the aspartic acid at ...
    • Buonanno, Andres (1978)
      This report describes the develpment of a direct, spectrophotometric assay for arginase. The assay may be conveniently used at high substrate concentrations (8Km) for assaying crude sources of arginase, and for steady-state ...
    • Vajdos, Felix F. (1991)
      A new method has been developed for estimating the extinction coefficient for a protein. The only information that is needed is the amino acid composition of the protein, and this is readily available if the gene coding ...
    • Siegel, Cecilie Ellen (1985)
      Texas has recently reentered the grape industry. A problem that confronts prospective vintners in Texas is that our soils have nutrition problems, especially the micronutrients. These deficiencies have led to reduced crop ...
    • Laurents, Douglas V. (1990)
      To study the contribution of disulfide bonds to protein stablity, a derivative of ribonuclease T1 (RNase T1) with both cystine residues reduced and methylated has been prepared using an improved procedure adapted from that ...
