Rabelomycin remained unchanged. 3) In controls without supplemented enzymes, the substrates remained unchanged.

Taken together, these results provide in vivo evidence for the function of HAL3A and HAL3B, and they point out the critical role of CoA biosynthesis during early postgerminative growth.

The bacterially expressed encoded proteins were characterized for their catalytic properties. Using these recombinant proteins, catalytic specificity was determined with the following substrates: XMP, xanthosine, xanthine, 1-methylxanthine, 3-methylxanthine, 7-methylxanthine, paraxanthine, theobromine, and theophylline (Fig. (Fig.3B–D;3B–D; Table TableI).I). CaMXMT2 catalyzed conversion of 7-methylxanthine to theobromine (Fig. (Fig.3C,3C, lane 2).

Purified CaXMT1 solely catalyzed conversion of xanthosine to 7-methylxanthosine (Fig. (Fig.3B,3B, lane 2). In contrast, crude CaXMT1 catalyzed conversion of xanthosine to 7-methylxanthine, suggesting that conversion of xanthosine to 7-methylxanthosine and that of 7-methylxanthosine to 7-methylxanthine successively occurred (Fig. (Fig.3B,3B, lane 4). Although the former reaction was catalyzed by CaMXT1, the latter was found to be catalyzed by a nonspecific purine-nucleoside phosphorylase derived from E. coli (Fig. (Fig.3B,3B, lane 6).
