SDS-PAGE and anoxic native-PAGE analysis consistently showed that the protein of the brown crystal was mainly composed of subunits (~60 kD) similar to those of OP Avl, while the protein of the brick red crystal was composed of ~20 kD subunits.

• SDS一和厌氧天然一队GE皆表明，棕色晶体主要由与Avl类似大小的亚基(一60 kD)组成，而砖红色晶体则主要由一20 kD亚基组成。
