YtvA
Protein DomainYtvA is a blue-light-sensing LOV-STAS photoreceptor from Bacillus subtilis whose LOV domain has been structurally analyzed for LOV-LOV dimerization and interdomain interactions. Homologous mutations in a conserved LOV hydrophobic pocket alter activation-state kinetics, supporting YtvA as a tunable LOV sensor domain relevant to optogenetic design.
