X-ray crystal structure of glycerol dibiphytanyl glycerol tetraether - macrocyclic archaeol synthase (GDGT-MAS) from Methanocaldococcus jannaschii with bacterial lipid substrate analog, 5'deoxyadenosine, and methionine bound

2-(HEXADECANOYLOXY)-1-[(PHOSPHONOOXY)METHYL]ETHYL HEXADECANOATE
1,2-DIPALMITOYL-SN-GLYCERO-3-PHOSPHATE; L-B,G-DIPALMITOYL-A-PHOSPHATIDIC ACID DISODIUM SALT; 3-SN-PHOSPHATIDIC ACID; 1,2-DIPALMITOYLDISODIUM SALT

Discovery, structure and mechanism of a tetraether lipid synthase.

The first 20 residues are from a tag and are denoted with negative numbers. The 21st residue, methionine, is the start of the native protein and has sequence number 1.
