P1 peroxisome
A subform of peroxisome that corresponds to an intermediate in a peroxisome assembly pathway, which operates by conversion of peroxisomal subforms in the direction P1, P2 -> P3 -> P4 -> P5 -> P6. P1 peroxisomes are distinguished from the other subforms on the bases of buoyant density and protein content; they contain fewer peroxisomal proteins than the other subforms.
