In Silico Characterization and Homology Modeling of a Cyanobacterial Phosphoenolpyruvate Carboxykinase Enzyme

Table 2

Parameters of cyanobacterial PEPCs calculated using the ProtParam program: molecular weight (MW) (g/mol); isoelectric point (pI); extinction coefficient (EC) (M⁻¹ cm⁻¹); instability index (Ii); aliphatic index (Ai); grand average hydropathy (GRAVY); number of negative residues (−R); number of positive residues (+R) [6].
