EC Tree
IUBMB Comments
An ATP-binding cassette (ABC) type transporter, characterized by the presence of two similar ATP-binding domains/proteins and two integral membrane domains/proteins. A bacterial enzyme that interacts with an extracytoplasmic substrate binding protein and mediates the high affinity uptake of phosphate anions. Unlike P-type ATPases, it does not undergo phosphorylation during the transport process.

malfunction
enzyme overexpression gives rise to multiple developmental defects including curly leaves with deep color, dwarfed stature, and reduced fertility. MPT3 overexpressing plants also accumulate higher ATP content, faster respiration rate and more reactive oxygen species than wild type plants
