E., Pratt, S. D., Katz, L., Severin, J. M., Holzman, T., and Park, C. H. (1998) Mol. vanx 89-93 mitochondrially encoded cytochrome c oxidase II Homo sapiens 28-34 15657055-8 2005 These spectroscopic studies also demonstrate that the metal ion in Co(II)-substituted VanX when complexed with a phosphinate analog of substrate D-Ala-D-Ala is also five-coordinate. vanx 86-90 mitochondrially encoded cytochrome c oxidase II Homo sapiens 67-73
