Cloned(Commentary)

Cloned (Comment) Organism
all 3 isozymes LH1-3, LH2 in 2 splicing variants, are expressed in as His-tagged proteins in Spodoptera frugiperda Sf9 cells via baculovirus infection system with the signal peptide at the N-terminus in isozymes LH2a and b and LH3 being exchanged for the signal peptide of isozyme LH1 Homo sapiens

Inhibitors

Inhibitors Comment Organism Structure
NaCl reduces the activity of the isozymes LH1, LH2a, LH2b, and LH3 with most of the synthetic nonpeptide substrates tested, in some cases the isozyme is activated or completely inhibited, overview Homo sapiens
