A key step in fungal biosynthesis of lysine, enzymatic reduction of α-aminoadipate at C6 to the semialdehyde, requires two gene products in Saccharomyces cerevisiae, Lys2 and Lys5. Here, we show that the kDa Lys5 is a specific posttranslational modification catalyst, using coenzyme A (CoASH) as a cosubstrate to phosphopantetheinylate Ser of the kDa Lys2 and activate it for Biosynthesis of lysine in Saccharomyces cervisiae: properties and spectrophotometric determination of homocitrate synthase activity.

There are two homocitrate synthases in Saccharomyces cerevisiae; both of them are feedback inhibited by L-lysine, but only one is repressed by L-lysine (Tucci & Ceci, I ). 5-Hydroxy-~~-lysine (DL-hydroxylysine) inhibits the growth of wild-type S ?doi=   Lysine Biosynthesis (Saccharomyces cerevisiae) From WikiPathways.
