| Accepted Name |
|---|
| Poly(3-hydroxybutyrate) depolymerase.
|
| Alternative Name(s) |
|---|
| PHB depolymerase. |
| Poly((R)-hydroxyalkanoic acid) depolymerase. |
| Poly(3HB) depolymerase. |
| Poly(HA(SCL)) depolymerase. |
| Poly(HA) depolymerase. |
| Reaction catalysed |
|---|
| ((R)-3-hydroxybutanoate)(n) + H(2)O <=> ((R)-3-hydroxybutanoate)(n-1 to 5) + ((R)-3-hydroxybutanoate)(1-5) |
| Comment(s) |
|---|
- Reaction also occurs with esters of other short-chain-length (C(1)-
C(5)) hydroxyalkanoic acids (HA).
- There are two types of polymers: native (intracellular) granules are
amorphous and have an intact surface layer; denatured (extracellular)
granules either have no surface layer or a damaged surface layer and
are partially crystalline.
