text: Yo, listen up, I got a story to tell,
  'Bout Escherichia coli diacylglycerol kinase, oh hell!
  It's a family of enzymes, integral membrane type,
  Unrelated to others, it's their own hype.
  
  We took it to the lab, determined the structure,
  With solution NMR, no need to rupture.
  The DAGK homotrimer, three-dimensional view,
  Transmembrane helix, something totally new.
  
  Check it out, the third helix got a swap,
  With the first and second, like a rap, non-stop.
  Three active sites, like a portico grand,
  Cornice on top, determining the lipid strand.
  
  Substrate specificity, that's the key,
  Overhangs the transfer site, near the water-membrane spree.
  Mutations in cysteine, causing misfolding so severe,
  Active site vibes, folding and catalysis, they interfere.
  
  Yo, DAGK's got the knowledge, it's in the groove,
  Integral membrane enzymes, breaking the rules.
  With the structure laid out, we're one step ahead,
  Escherichia coli DAGK, that's what I said!
