Biological Activity
FAICAR (0.005-0.3 mM) was used as substrate at 37°C, and recombinantly expressed C. neoformans ATIC exhibits IMP cyclohydrolase activity with a Km_app of 30 μM, Vmax of 8.6 U/mg, and kcat of 7.7 s−1[1].
FAICAR (0.1-4 μM) acts as a substrate for human AICAR transformylase-IMP cyclohydrolase's IMP cyclohydrolase domain, with a Ks of 0.87 μM at pH 7.4, and supports an IMP cyclohydrolase specific activity of 29.5 nmol IMP formed/min/μg protein at a concentration of 4 μM[2].
