Figure 2. Small molecule methyltransferase TMT1 is a sequence homolog of Crg1.
(A) Tmt1, a sequence homolog of Crg1, modifies small molecule intermediates of TCA cycle (trans-aconitate) and leucine biosynthesis (3-isopropylmalate and isopropylmaleate) to form methyl esters. (B) Hypothetical methylation of cantharidin by Crg1.
