LOCUS       sequence-256053-        5767 bp    DNA     circular SYN 15-DEC-2025
DEFINITION  Slow cycling (open for minutes) step-function artificial anion 
            conducting channelrhodopsin (aACR). High light sensitivity. 
            Activation with blue to green light, inactivation max with 605 nm 
            (accelarates closure to ms). Codon optimized for mammalian 
            expression..
