2tpl Summary



The structure was published by Sundararaju, B., Antson, A.A., Phillips, R.S., et al., Gollnick, P., Dodson, G.G., and Wilson, K.S., in 1997 in a paper entitled "The crystal structure of Citrobacter freundii tyrosine phenol-lyase complexed with 3-(4'-hydroxyphenyl)propionic acid, together with site-directed mutagenesis and kinetic analysis, demonstrates that arginine 381 is required for substrate specificity." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.5 Å and deposited in 1997.

The experimental data on which the structure is based was also deposited.
