Theoretical pi

Webb14 nov. 2015 · As PIP-DB contains legacy data, not all entries were deemed useful. Initially, we isolated entries with a single measured isoelectric point rather than entries with multiple pI values or a range of values. Estimation of theoretical pI values was undertaken on the unique protein subset. Pearson correlation coefficients and root-mean square … Webb9 juni 2016 · The theoretical pI is based on the primary sequence, but is unlikely to match the actual pI because some of the charged side chains are either buried or in salt …
