Gao_Ppl

Description

Gao_Ppl or Ppl system is a single gene system. This system was discovered among others in (N/A) . This single gene system is described with 2 different domains: PHP (Polymerase and Histidinol Phosphatase) which is a putative nuclease and an ATPase domain.

Molecular mechanism

As far as we are aware, the molecular mechanism is unknown.

Example of genomic structure

The Gao_Ppl is composed of 1 protein: PplA.

Here is an example found in the RefSeq database:
