%X The process e(+)e(-) -> p (p) over bar gamma is studied using 469 fb(-1) of integrated luminosity collected with the BABAR detector at the SLAC National Accelerator Laboratory, at an e(+)e(-) center-of-mass energy of 10.6 GeV. From the analysis of the p (p) over bar invariant mass spectrum, the energy dependence of the cross section for e(+)e(-) -> p (p) over bar is measured from threshold to 4.5 GeV. The energy dependence of the ratio of electric and magnetic form factors, vertical bar G(E)/G(M)vertical bar, and the asymmetry in the proton angular distribution are measured for p (p) over bar masses below 3 GeV. We also measure the branching fractions for the decays J/psi -> p (p) over bar and psi(2S) -> p (p) over bar are also determined.
