Phosphopeptides

Peptides containing phospho-serine, phospho-threonine and/or
phospho-tyrosine are useful in replicating phospho-protein
downstream effects. Crefu Peptides can provide one, two or multiple
phospholation sites phosphopeptides to meet researcher different
needs via uses protected and modified phosphoamino-acid:
Fmoc- AA(PO(OBzl)OH)-OH (AA=Ser,Thr or Tyr).


Phospho-serine	Phospho-threonine	Phospho-tyrosine

Sulfated peptides

Sulfurylation at Ser, Thr and Tyr is another modifcation of amino acids in nature. Activity of many enzymes
depends on the oxidation state of SH-groups in these residues.


Sulfurylation at serine	Sulfurylation at threonine	Sulfurylation at tyrosine
