Basic Concept behind STRENDA DB Before entering example data, Carsten Kettner describes the basic concept behind STRENDA DB which reflects substantially the common structure of a manuscript. For the data input, STRENDA DB requires header data (the title of the manuscript and the name(s) of the author(s), data on the protein assayed, information on the methodology used and techniques applied including details on the assay conditions and results data that describe the kinetic activity of the enzyme. In a first step, it is demonstrated how to create a Manuscript in STRENDA DB including the input of the header data.
