text: Yo, check it out, I'm 'bout to drop some knowledge,
  Talkin' 'bout the Calvin cycle enzymes in college.
  We got GAPDH and PRK in the mix,
  Formin' a complex with CP12, that's the fix.
  
  When it's oxidizing, they all come together,
  Inhibitin' activities, that's the tether.
  But don't worry, reduced thioredoxins save the day,
  Restorin' GAPDH and PRK, okay?
  
  We studied eight isoforms of thioredoxins,
  TRX f1, m1, m2, m3, m4, y1, y2, and x, no omissions.
  Arabidopsis thaliana, representin' the crew,
  Investigatin' how these proteins do.
  
  In the complex, A(4)-GAPDH and PRK,
  Activated by TRX f1, no delay.
  M1 and M2, they work a bit slower,
  But the other TRXs, they couldn't go any lower.
  
  PRK on its own gets regulated, you see,
  By TRX f1, m1, or m2, set it free.
  But B(4)- and B(8)-GAPDH, they got a specific need,
  Only TRX f1 can make 'em succeed.
  
  Interesting fact, PRK in the complex,
  Gets activated faster, no time to flex.
  A(4)-GAPDH in the mix, it's a breeze,
  Faster and easier to activate, that's the keys.
  
  The CP12 complex, a reservoir of inhibition,
  Ready to be released, active enzymes in transition.
  When the shift from dark to low light takes place,
  TRXs come through, breakin' the complex's embrace.
  
  But for GAPDH with B-containing isoforms,
  Autonomous redox-modulation performs.
  Perfect for conditions of active photosynthesis,
  These enzymes adapt, showin' their uniqueness.
  
  So there you have it, the rap version of the passage,
  All the content intact, no need for massage.
  Calvin cycle enzymes and thioredoxins on display,
  In the language of rap, we've had our say.
