Lysine biosynthesis in Saccharomyces cerevisiae: mechanism of alpha-aminoadipate reductase (Lys2) involves posttranslational phosphopantetheinylation by Lys5.

A key step in fungal biosynthesis of lysine, enzymatic reduction of alpha-aminoadipate at C6 to the semialdehyde, requires two gene products in Saccharomyces cerevisiae, Lys2 and Lys5. Here, we show that the 31-kDa Lys5 is a specific posttranslational modification catalyst, using coenzyme A (CoASH) as a cosubstrate to phosphopantetheinylate Ser880 of the 155-kDa Lys2 and activate it for catalysis. Lys2 was subcloned from S. cerevisiae and expressed in and purified from Escherichia coli as a full-length 155-kDa enzyme, as a 105-kDa adenylation/peptidyl carrier protein (A/PCP) fragment (residues 1-924), and as a 14-kDa PCP fragment (residues 809-924). The apo-PCP fragment was covalently modified to phosphopantetheinylated holo-PCP by pure Lys5 and CoASH with a Km of 1 microM and kcat of 3 min-1 for both the PCP and CoASH substrates. The adenylation domain of the A/PCP fragment activated S-carboxymethyl-L-cysteine (kcat/Km = 840 mM-1 min-1) at 16% the efficiency of L-alpha-aminoadipate in [32P]PPi/ATP exchange assays. The holo form of the A/PCP 105-kDa fragment of Lys2 covalently aminoacylated itself with [35S]S-carboxymethyl-L-cysteine. Addition of NADPH discharged the covalent acyl-S-PCP Lys2, consistent with a reductive cleavage of the acyl-S-enzyme intermediate. These results identify the Lys5/Lys2 pair as a two-component system in which Lys5 covalently primes Lys2, allowing alpha-aminoadipate reductase activity by holo-Lys2 with catalytic cycles of autoaminoacylation and reductive cleavage. This is a novel mechanism for a fungal enzyme essential for amino acid metabolism. << Less

The pcd gene from Flavobacterium lutescens IFO3084 encoding Delta'-piperideine-6-carboxylate dehydrogenase (PCD) was cloned, sequenced, and expressed in Escherichia coli. The deduced amino acid sequence of PCD from F. lutescens IFO3084 showed strong similarity to that from Streptomyces clavuligerus. The molecular mass of the recombinant PCD was estimated to be approximately 58,000 Da by SDS-PAGE and native PAGE, which indicated that the enzyme molecule is a monomer. The in vitro analysis of L-alpha-aminoadipic acid (L-AAA) production showed that L-AAA is synthesized from L-lysine in two steps catalyzed by L-lysine 6-aminotransferase (LAT) and PCD from F. lutescens IFO3084. << Less
