Destroy Gameobject once 0 health

i have a simple destroy script and a enemy Health script i want to re design the destroy script to find the enemy health and destroy the one with 0 health

enemy death script (simple destroy)

 using UnityEngine;
 using System.Collections;
 
 public class DestroyBasic : MonoBehaviour
 {
     void Update ()
     {
         if(Input.GetKey(KeyCode.Space))
         {
             Destroy(gameObject);
         }
     }
 }
 
 
 EnemyHealth script
 
 
 /// 
 /// EnemyHealth.cs
 /// A basic script display the health of a mob in game
 /// 
 /// This script is ment to be attached to a mob, or a mob prefab
 /// 
 using UnityEngine;
 using System.Collections;
 
 public class EnemyHealth : MonoBehaviour {
     public int maxHealth = 100;
     public int curHealth = 100;
     
     public float healthBarLength;
 
     // Use this for initialization
     void Start () {
         healthBarLength = Screen.width / 2;
     }
     
     // Update is called once per frame
     void Update () {
         AddjustCurrentHealth(0);
     }
     
     void OnGUI() {
         GUI.Box(new Rect(10, 40, healthBarLength, 20), curHealth + "/" + maxHealth);
     }
     
     public void AddjustCurrentHealth(int adj) {
         curHealth += adj;
         
         if(curHealth < 0)
             curHealth = 0;
         
         if(curHealth > maxHealth)
             curHealth = maxHealth;
         
         if(maxHealth < 1)
             maxHealth = 1;
         
         healthBarLength = (Screen.width / 2) * (curHealth / (float)maxHealth);
     }
 }

if i dont need to have a separate script how would i add the destroy on 0 hp to EnemyHealth script
