additional information
R85V
complete loss of activity with citrate, retains activity with isocitrate
R85V
Thermus thermophilus HB27 / ATCC BAA-163 / DSM 7039
-
complete loss of activity with citrate, retains activity with isocitrate
-
additional information
-
deletion of A80, inability of mutant to use 3-isopropylmalate, isocitrate is 4fold preferred over homoisocitrate
additional information
generation of a gene-disruption TK0280 deletion mutan strain, functional complementation by expression of the gene icdh from Thermus thermophilus strain Hb27, but not by genes hicdh and leuB from this organism
