摘要:
4-(Indol-3-ylmethyl)-4-hydroxy-2-oxoglutarate, which is useful as an intermediate in the synthesis of monatin, may be synthesized from indole pyruvic acid and pyruvic acid (and/or oxalacetic acid) by using a novel aldolase derived from the genus Pseudomonas, Erwinia, Flavobacterium, or Xanthomonas.
摘要:
The present invention relates to a process for producing efficiently glutamic acid derivatives (including salts thereof) such as monatin by converting a substituted α-keto acid of formula (1) into a glutamic acid derivative of formula (2) in the presence of an enzyme catalyzing conversion of the same.

摘要:
According to one embodiment, a microprobe includes a supporting base, an insulating layer, and an electrode layer arrayed in a first direction in this order. A principal surface of the microprobe is formed in a second direction different from the first direction. A step is formed on at least the electrode layer on the principal surface, and the electrode layer is partitioned into a first area and a second area by the step.
