Part:BBa_K5097009
SpeA (arginine decarboxylase)
Usage and Biology
This specific part codes for SpeA gene from E.coli. It expresses the enzyme arginine decarboxylase (Shaibe et al., 1985). This enzyme catalyzes the conversion of L-arginine into agmatine and carbon dioxide, the first step in the metabolic pathway that converts arginine into putrescine (Morris et al., 1969). The 2024 Oneonta iGEM designed this sequence for use in a base producing circuit. This part when co-expressed with SpeB (BBa_K0597010) will construct this pathway and produce putrescine from arginine.

This gene sequence has been altered to make the SpeA gene RCF10 compatible. To do this, we removed an internal PstI restriction sites, as follows G291A, T1170G, G1434A. These changes will not impact the amino acid sequence.
