All samples were also subjected to mitochondrial and nuclear DNA typing by analyzing polymorphisms in the cytochrome oxidase subunit II (COII7) and the glucose-phosphate isomerase (GPI8) genes, respectively.
(48) Ohishi in our laboratory indicated that GPI transamidase is a protein complex by demonstrating that GPAA1 forms a complex with GPI8 (now termed PIG-K), (49) which is a catalytic component of GPI transamidase.
The Conzelmann group identified yeast GPI8 as a catalytic component of GPI transamidase.
(2001) PIG-S and PIG-T, essential for GPI anchor attachment to proteins, form a complex with GAA1 and GPI8. EMBO J.
