- * Plant hemoglobins signature *
- *******************************
-
- Leghemoglobins [1] are hemoproteins present in the root nodules of leguminous
- plants. Leghemoglobins are structurally and functionally related to hemoglobin
- and myoglobin. By providing oxygen to the bacteroids, they are essential for
- symbiotic nitrogen fixation. Structurally related hemoglobins from the nodules
- of non-leguminous plants [2,3], and from the roots of non-nodulating plants
- [4] have been recently sequenced. We have developed a signature pattern that
- picks up the sequence of plants hemoglobins, exclusively.
-
- -Consensus pattern: [SN]-P-x-L-x(2)-H-A-x(3)-F
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
- -Last update: April 1990 / Pattern and text revised.
