bilirubin-glucuronoside glucuronosyltransferase

bil·i·ru·bin-glu·cu·ron·o·side glu·cu·ron·o·syl·trans·fer·ase

(bil'i-rū'bin-glū'kū-ron' ō-sīd glū'kō-ron'ō-sīl tranz'fĕr-ās),
Bilirubin monoglucuronide transglucuronidase; a transferase that transfers a glucuronoside from one molecule of bilirubin glucuronoside to another, forming bilirubin bisglucuronoside and unconjugated bilirubin (a step in heme catabolism).
