CATH Superfamily 3.40.50.1820

Alpha/Beta hydrolase fold, catalytic domain

The name of this superfamily has been modified since the most recent official CATH+ release (v4_3_0). At the point of the last release, this superfamily was named:

"
alpha/beta hydrolase
".

FunFam 25: putative methylesterase 11, chloroplastic

There are 2 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
(R)-mandelonitrile lyase. [EC: 4.1.2.10]
(R)-mandelonitrile = cyanide + benzaldehyde.
  • A variety of enzymes from different sources and with different properties.
  • Some are flavoproteins, others are not.
  • Active toward a number of aromatic and aliphatic hydroxynitriles (cyanohydrins).

Pheophorbidase. [EC: 3.1.1.82]
Pheophorbide a + H(2)O = pyropheophorbide a + methanol + CO(2).
  • Forms part of the chlorophyll degradation pathway, and is found in higher plants and in algae.
  • In higher plants it participates in de-greening processes such as fruit ripening, leaf senescence, and flowering.
  • Exists in two forms: type 1 is induced by senescence whereas type 2 is constitutively expressed.
  • Highly specific for pheophorbide as substrate (with a preference for pheophorbide a over pheophorbide b) as other chlorophyll derivatives such as protochlorophyllide a, pheophytin a and c, chlorophyll a and b, and chlorophyllide a cannot act as substrates.
  • Another enzyme, called pheophorbide demethoxycarbonylase (PDC), produces pyropheophorbide a from pheophorbide a without forming an intermediate although the precise reaction is not yet known.
