Abstract
Polyhydroxyalkanoates (PHA) are polyesters of various hydroxyl alkanoates that are synthesized by many gram-positive and gram-negative bacteria from about 75 different genera. PHA genes database is a repository of genes and its genomic information related to PHA. It contains data on the genomic characterization of intermediates of PHA. These include CAB genes, responsible for biodegradable plastic synthesis. The genomic database provides data on PHA genes from archaeal, bacterial and eukaryotic genomes.
