Legal Question in Business Law in Texas

Your question is not clear - the way it is phrased, it may be asking whether it is possible for you to ACT as a notary for your own business (for your signature or another officer/board member), or whether you may sign for your business before a notary.

Can you act as a notary for your own business?

No. If you were considering notarizing your own signature, that is entirely improper. But even if the signer is a partner, another officer, a board member, etc., who is signing for the business, you may not do so. Any notary who is a party to a transaction, or has a direct or indirect financial or other beneficial interest in the transaction, must not notarize a document. In your case, you are an interested party in ANY transaction by your own business.

Can I sign for my business before a notary?

Of course, as long as you hold a position in your business (and assuming no other approval but yours is needed, or your board has approved the signature) where you are authorized to sign the document.
