Figure 1From: Branched-chain amino acid aminotransferase and methionine formation in Mycobacterium tuberculosisThe formation of Met from KMTB. The pathway of polyamine synthesis and subsequent Met regeneration from MTA, as known from K. pneumoniae [11] and B. subtilis [12], is shown. Solid arrows represent steps that have been characterised in M. tuberculosis (present study and [21]). The conversion of KMTB to Met is shown at the top in bold. KIC = ketoisocaproate, KIV = ketoisovalerate, and KMV = ketomethylvalerate.Back to article page
