31. It is characterized by the presence of two leucine residues in its intracellular trafficking. 32. It also contains leucine -rich repeats with conserved cysteine-rich flanking sequences. 33. It contains a basic region-leucine zipper ( bZIP )-like domain. 34. TBRG4 also contains multiple putative leucine zipper domains. 35. Their protein structures resemble small leucine -rich proteoglycans found in the extracellular matrix. 36. Leucine on the left and photoleucine on the right37. L-Photo-Leucine acquires its function after being affected by UV light. 38. Through the leucine zipper structures, sMafs form homodimers by themselves and Bach families. 39. Leucine at a dose exceeding 500 mg / kg / d was observed with hyperammonemia.40. Leucine is a potent activator of mTORC1.
