Description
PPX2 Homolog
Name:Exopolyphosphatase
Locus tag: MLP_44770
Function:
There are two types of exopolyphosphatase, PPX1 and PPX2, both of which mediate the hydrolysis of the terminal phosphate of a polyphosphate chain. [1]
In
Microlunatus phosphovorus: While most Actinobacteria species have both PPX1 and PPX2,
M. phosphovorus only has one PPX2 homolog. [1]
Cofactors and Modifications: There are currently no known cofactors and modifications of the PPX2 homolog in M. phosphovorus.
3-D Structure:
C-score: 1.01
The three-dimensional structure was predicted using the I-TASSER software [3]. All images shown are the models with the highest confidence, which is quantitatively measured with a C-score that typically falls within the range [-5,2], in which 2 represents the highest level of confidence, and -5 represents the lowest level of confidence.
Gene length: 945 base pairs [4]
Protein size:33.0 kDa [4]
pH Range The PPX2 homolog in M. phosphovorus has yet to be characterized, and so there is no data for the pH range in which it functions.
Temperature Range The PPX2 homolog in M. phosphovorus has yet to be characterized, and so there is no data for the temperature range in which it functions.
