Several yeast systems have recently been developed for the recombinant production of gelatin and collagen. Amino acid sequence-specific prolyl 4-hydroxylation is essential for the gel-forming capacity of gelatin and for the proper folding of (pro)collagen. This post-translational modification is generally considered to be absent in microbial eukaryotic systems and therefore co-expression of heterologous (human or animal) prolyl 4-hydroxylase would be required. However, we found that the well-known protein expression host Hansenula polymorpha unexpectedly does have the endogenous capacity for prolyl 4-hydroxylation. Without co-expression of a heterologous prolyl 4-hydroxylase, both an endogenous collagen-like protein and a heterologously expressed collagen fragment were found to be sequence-specifically hydroxylated.
