Dear Ali Gouran ,

Yes, they're the same. P in P-cluster simply stands for phosphorous.

Musab Isak

Yes, the words "P-cluster" and "phosphorus cluster" are equivalent in nitrogenase enzymes and refer to the same entity.

Lungelo Khanyile

In chemical symbols, P is for Phosphorus, so P and phosphorus cluster are the same terms.
