Message definition (Pyridoxal phosphate)
In transamination, after deprotonation the quinonoid intermediate accepts a proton at a different position to become a [[ketimine]]. The resulting ketimine is hydrolysed so that the amino group remains on the complex. In addition, PLP is used by aminotransferases (or transaminases) that act upon unusual sugars such as [[perosamine]] and [[desosamine]]. In these reactions, the PLP reacts with [[glutamate]], which transfers its alpha-amino group to PLP to make pyridoxamine phosphate (PMP).  PMP then transfers its nitrogen to the sugar, making an [[amino sugar]].
