Structural alignment of human HRASLS enzymes. Sequence alignment was performed using ClustalW2 [51] and structural alignment was performed for HRASLS2, HRASLS3, and HRASLS4 as described by Golczak et al. in 2012 [3] and Wei et al. in 2015 [6]. The β-sheets are indicated by green arrows and α-helices are indicated by red lines
