Hello academics

I would just like to know if anyone is currently working with SUSY7/Ura3 mutant yeast ( S. cerevisiae ) strain especially in any East Asian countries? I need that yeast strain but so far have not been able to find it anywhere close by. If anyone knows or can direct me to someone or some company etc where I could get my hands on that particular strain, please let me know through the comments. Any form of help or direction would be much appreciated. Thank you so much in advance.
