"text": "<p>This presumed domain (used to be named as DUF39) is about is about 360 residues long. The function of this domain is not clear. It is found at N terminus in some proteins that have two C-terminal cystathionine beta-synthase (CBS) domains, such as MJ0100 from Methanocaldococcus jannaschii. This domain can also be found in proteins that contain two C-terminal inserted Fe4S domains [[cite:PUB00093781]].</p>\n\n<p>In Methanocaldococcus jannaschii, MJ0100 and its ortholog MA1821 from Methanosarcina acetivorans are involved in Hcy (homocysteine) biosynthesis. MJ0100 CBS domains bind S-adenosyl-l-methionine (SAM) and 5'-methylthioadenosine (MTA), which induce a conformational change consistent with regulatory function. Another protein in the homocysteine biosynthesis pathway, MJ0099 and its ortholog MA1822, is involved in the reduction of the disulfide formed in MJ0100/MA1821 during the conversion of Asa (aspartate semialdehyde) to Hcy [[cite:PUB00078766], [cite:PUB00093781]].</p>\n\n<p>The DUF39-CBS and DUF39-ferredoxin architectures repeatedly occur together in the genomes of methanogenic Archaea, suggesting they may be of diverged function. This is consistent with a phylogenetic reconstruction of the DUF39 family, which clearly distinguishes the CBS-associated and ferredoxin-associated DUF39s [[cite:PUB00078766]].</p>",
